Well, the sales volume of the PS3 isn't as high as expected... since 600€ ( 750$? ) isn't something everybody can afford!
By the other hand, the
famous remake of FFVII would be a good reason for lots of people to buy the PS3... at least, I would consider the idea.
But I won't make further discussion about it, 'cause I still doubt the remake will be made.
I hope they make it though.
