I still love FFVII but the longer it has been, the more I dislike the materia system. It gives no motivation to use all but your favorite characters. I had a similar problem with FFVIII.
Those character similarities are very striking, I am still not that worried. I mean, if the games sucks, it will just save me the cost of a PS3 FFXIII. If it is good, it is still highly likely I won't buy a PS3. So I will just sit and wait and hope something good comes out of it.
