Ok I had to pull this up, today there was a nintendo direct focused only upon the new smash bros and for this case, there was a load of new stuff revealed:
3ds version is coming this summer
Wii-u in winter
Both games will run at 60 FPS, even on the 3ds, the solution was on the 3ds, make the characters move at 60 frames, all other stuff like assist trophies and pokemon move at 30.
Both games will share the same roster, only difference is again stages, those which originated on console titles will be on the wii u and those on the 3ds those that originated from games on portable systems. The only exceptions are staple stages like battlefield, final destination, and past smash bros stages, some from melee for instance will be on the 3ds.
final destination is so popular, it has various skins such as for mario galaxy, metroid, and so on.
Online is much more improved.
In friends, you can go crazy.
With random people: they simplified the modes, for fun and for glory
for fun: the casual mode, has both timed and stock matches, has items and all stages, only tracks wins, no skill tracking
for glory: the competitive mode, has only stock matches, possible one on one fights, only stage is final destination and its skins, though if its demanded or wanted, they may update it with other "stable stages" like battlefield or the boxing ring, stages without random events. Tracks wins and losses, no items, its pure skill.
There are no competitive ranks, but the game will have a matchmaking skill tracker similar to that of other games like Halo. It will work in both for fun and glory modes.
Final smashes are back, save this time, characters like Samus do not revert to zero suit for good reason.
Characters like Zero suit and Shiek are their own roster characters now with new moves.
Zero suit samus returns, has updated moves and is more manervable with jet boots. Her design is based on the metroid prime samus rather than the other M one used for her normal incarnation in this game
Shiek is back with 2 new moves as well, a cluster grenade reminest of Snakes grenades and a heel kick, Zelda's new down special is summoning a phantom from spirit tracks to defend or take a hit for her.
Yoshi is back as well, but his case was special, he has new moves but wasn't revealed till now due to software issues and a small redesign, he stands upright now due to the need to work with a software of other characters.
Many returning characters have some new updates like Kirby can charge his hammer now and move with it while charging making him a much bigger threat. His final smash is the giga sword, an oversized sword crushing everything on screen. DeDeDe still has his jet hammer but now instead always throws gordos instead of waddle dees, these can be easily reflected or kicked away though.
Pit has less acrobatic stuff but is still swift.
Lucario is back and his aura ability makes him stronger and faster but it can be too much causing you to loose control. His final smash is mega lucario making him have full power regardless for a short time.
Olimar is different as well, his pikmin count has been reduced to 3 but all 5 colors are still in, they are pulled in a fixed order, red, yellow, blue, white, and purple so its easier to manage him. His recovery is also much better, he has winged pikmin fly him up, but if he has 3 or rather a purple pikmin, his recovery doesn't go as high. His own ship is now an item for one to use against others rather than his final smash.
For new characters: They wanted to make a new feel to many of them, this includes
Rosalina and Luma, the luma can be unleashed and copy your every moves as rosalina
Little mac, practically unstoppable on the ground, but terrible in the air and in recovery, basically for all the power he has, once knocked out of the ring, he suffers more than anyone in midair.
Megaman- all his moves are based on various robot masters, his normal attack and forward smash are his buster shots, but he has actual melee moves. His specials include metal mans blades, crash mans crash bombs working like the gooey bombs, leafmans leaf shield
Wii fit trainer has both a female and male model to use, no differences in power or height. Unique in that it has the power to charge a projectile like samus for later and then use a breathing move to enhance attacks for a short time, a rather weak but swift character with these two moves can call upon higher power for a short time.
Villager is a clown, his net traps people, he can shoot, and ride on his gyroid, his up special is ballon fight, and his down special is planting a tree and making a barrier weapon out of it.
Theres also the notion of custom move sets for local and online friend play, what they displayed was a short difference with marios fireballs, normally is moves at a simple speed and bounces, but one shot had him throw a very large and slow moving fireball, and another a longer ranged very small and fast fireball with no loss in height, otherwise also kirby using freeze breath instead of swallowing opponents (short mention that none of his copy hats have been seen yet). They will reveal more of this later on.
Many items return, among them the pokeballs have a difference, master balls appear for legendary or rare ones now, some of the new ones include the recent gen 6 pokemon from x and y including the legendaries. On the normal pokeballs, same deal, non legendary pokemon are in from as recent as gen 6 as well.
Assist trophies are back as well
Many favorites like the beamsword, mine, and bumper return. New ones like the fire wand blocks from mario, the fairies in a bottle from zelda, and others come in as well.
For the 3ds, there is a unique mode called smash run, its basically the same built off of a mode called city trail from an old game called kirby air ride, but in this one, players start out scattered around a map with various rooms and entrances and exits, in this mode they face AI enemies from various series like mario, zelda, metroid, pikmin, etc to gather stickers that power them up in speed, jump, strength, weight, and so on. Some enemies from brawls single player adventure also appear. Players run in this for 5 mins defualt or longer if they set it to that, and then face off in an either (random by default) or fixed event if the their settings are put out like that. They then face off in an event like simply fighting, but also racing, long jumping, escaping, home run derby, and so on.
Finally 2 other characters:
Returning is the most popular (in my case overrated) pokemon, Charizard by himself. He has his similar moveset from brawl, but his final smash is his mega evolution.
WARNING NEW CHALLENGER APPORACHING

Yep thats right this guy is in the game, the most popular starter of the 6th gen is joined the fight, now with lucario, looks like theres a good amount of company for pikachu this game. Greninja has joined the smash bros team.
