All great choices for remakes.
As far as FF7 goes, I think the smartest thing Sony could do is work with SE and get a FF7 remake released at launch for the PS4. If it was a really good game (heck probably even if it was only mediocre), I think we all know who would win next gen. Well ok, Sony would have to keep good software coming out afterwards, but recently they haven't had a problem with that.
