the reason that ff7 is not getting - nor ever will get a sequal is BEACUSE its good. Square has stated lots of times that if they did make a sequal it most likely wont live up to expectaions to such a popular game and they dont want to dispoint fans with a sub-par sequal, (and the fact that they would need a new engine to make it on) while ff10 is good in some peoples eyes, many fans wouldnt be disapointed by a sub-par sequal to it, and the engine is already there (and plus they needed something to do while ff11 is being screwed around)
