I suspect the cartoony look will go, and some of the charm with it. It's risky, but also pretty exciting. This is FF7 for a new generation of gamers and elements are bound to be different.
My favourite is FF6 and I wouldn't like a current remake of that, but FF7 should lend itself better to a revamp.
An FFVI remake in the style of FFIV DS on the 3DS would be great. Give it the same brutal difficulty as that and it would be amazing.

To be able to explore what I wanted how I wanted was such an epic thing. To go and breed your own golden chocobo to find that Kings of the Round materia on your own with no guide or internet to tell you how to do it gave a massive sense of achievement.
all would be fine
