Ya know, if they really wanted to remake VII, why not just go the route Nintendo is with StarFox 64 and Ocarina of Time? Namely, put it on the 3DS with only slightly improved visuals. Not like they'd have trouble fitting it on the 3DS game card, which does have a capacity ranging from 2GB to 8GB. Hell, with that amount of memory, why not put Before Crisis and Crisis Core on the card too? A FFVII Collection, if you will, in 3D.
Not like they're going to, but still. It's a thought.
