While not implementing it wouldn't particularly bother me, I think it's a smart decision to do so. People used to the way current generation games work will have a hard time coming around to the idea of not being able to use the camera, even if the game was originally designed that way - especially new players.
I don't understand what's taking so long if they're not implementing new features. If a group of random people on forums can redo all the textures for FF7 in their spare time, what is taking so long for what I assume is a team of professionals working at least 32-40 hours a week? Granted, there are a shitload more textures in FFX to redo...
I've just had a thought. This game will probably be built to support widescreen, which the original did not, which slightly adds to the work (realignment of elements etc) but what if they're redoing the FMV's? I'm assuming they weren't built in widescreen environments, and it would be shoddy to jump from 16:9/10 to a 4:3 aspect ratio, though I wouldn't be surprised if they did this.
I'm just surprised there hasn't even been a trailer yet, I don't understand!
