don't jump too early... to me she looks like praying for Naruto's safety.. She stays at home and waiting for him. I hope not but it's a chance that we cannot deny...
It's a chance, but to me it definitely doesn't look like that, specially because it wouldn't make much sense. Since the beginning, it has been said that Hinata is supposed to be the future leader of the Hyugas. So I don't see why that wouldn't happen. About Naruto having a home wife... hmm.... meeh.... My expectations are still low but to me, it looks like Hinata will be more focused on Hyugas.
Not everyone has the raw talent and sense to become a prodigy. You need some kind of equilibrium between the aspiring underdogs who have to practice for years to get somewhere and the geniuses that have everything as coming natural to them in a short period of time. For Hinata, Neji is not a weak benchmark to have. He was always one of the more advanced and capable shinobi out of the K11. If she can refine her own style of combat while perfecting the unqiue clan abilities of the Hyuga like Neji did, then there are a number of opportunities that become available to her - to surpass just SRA Neji would put her above most of her female classmates and a few of the boys. Given the fact that Hinata was never intended to be a powerhouse, it's not an unimpressive accomplishment.
Yes, but she has the guts to say she has the same nindo as Naruto, and haven't improved much. He's not supposed to be a genius too, and he is one of the strongest shinobis ever if not the one, and she keeps saying his quotes while fighting like a scared bunny. Her improvement was awful, seriously, take Ino as a reference. She is nor a genius or has Naruto's nindo, but she has improved much more than Hinata, much more. Ino was like... nothing in pt 1, now, she can make transmissions to the whole shinobi alliance and is also a medical ninja (not as good as Sakura, of course). That's improvement. Being able to use Byakugan taijutsu and then, with a loot of effort, doing 64 palms once and getting exhausted is not.
Stats wise, Hinata's the second strongest out of the leaf kunoichi, only behind Sakura. Add Temari in there, then she's the third strongest. So she's really not doing that bad, per se.
Power couple 
I don't think so. I find Temari much stronger tbh. And Konoha young girls are not a good reference of power, just Sakura. But take a look at Anko, Tsunade, Kurenai..... Hinata is nothing compared to them.
