They're pretty much stuck in an impossible situation. JRPGs have really declined unfortunately and Square in general has been losing fans who feel they've gone into a bad direction. It'll be tough for them to make anything on the same level of worldwide appeal and even if they do when they remake FF7 it'd be upgraded to current gen standard which they say would take a lot of time and resources. There will undoubtedly be people unhappy with the remake as well and it likely won't see the same success or appeal the original had.
