I don't understand this belaboured point of yours, Lupus. Nomura adheres to his own style when designing characters. What is the problem with that? All artists stick to their own style most of the time. I can understand disliking his designs but saying that an artist has a particular style as if it's in any way noteworthy as a bad thing is very curious. Furthermore, saying that Amano should return as the character designer because his clearly better and then using his sketchy, impossibly stylised (as in, such designs could never be used in a videogame and probably wouldn't work even if they were) re-workings of Nomura designs to back your opinion seems a little silly.
I don't know why you trust the collective opinion of 2chan, Chrono Mizaki. They've slated every single Final Fantasy game since the tenth instalment. It's not unlikely that they simply prefer the older games and view any updating of the series as heretical. I wouldn't recommend taking too seriously the opinions of a clutch of hysterical, puritanical obsessives.
I am, of course, looking forward to FFXIII. Every preview of the game has been positive, it has been well received in Japan (over one million copies sold in one day) and all of the videos and information about the game suggest that will be fantastic. I must admit that I am disappointed that they have abandoned FFXII's battle system (instead of just upgrading it) and have strayed away from the accomplished, stunning artistry of FFXII but there is no show like a Final Fantasy show and I feel assured that FFXIII will be a genre-defining game :]
