Sasuke will end up with Karin, we all know he's in love with Naruto and we all know Naruto loves him as a brother, So Karin is the next best choice, did nobody see Sasuke's reaction when he found out Karin was part of the Uzumaki Clan? His interest in her peaked tenfolds....lol
Okay joking aside, if Sakura end up with Sasuke, i'll just have to deal, you just have to hope that if that does happen, Sasuke actually does something to redeem himself in her eyes, and show us that he actually deserves her. It's like with Hinata, until the point where she slapped Naruto to knock him out of his depression, I didn't consider the pairing as being worthy at all, she was too soft, and even if they got married, you got the feeling it would be Sakura's responsibility to make sure he ate healthy, did his paperwork attend his meetings on time, not blow all the budget on Ramen etc. Hinata never showed she had it in her to make sure Naruto doesn't do something rash, now I have a bit more confidence in her, even if she is a bit too Naruto focused to a point it's still too unhealthy.
The way Sasuke has behaved has not been great and he needs to show some major changes to even be considered worthy, and it's not just Sasuke sakura needs to show some changes in behaviour as well, she becomes too meek around him, not confident in her abilities, her brain switches off and she acts irrationally, to prove she's no longer a weakling, and she never talks back at him, that needs to change with her, she needs to act like she acts around Naruto, at ease with herself, knock some sense into him when he's being a git which is every other panel.
I still can't see it happenning but if it does i'll be dissapointed and move on, though i'll be less likely to read his next work, for me atleast if I'm really dissapointed in the end it takes allot of motivation to get be remotely interested in the piece of work,
