All Zelda games. Take OOT and MM 3D and just up the resolution and I'd be happy, but I would seriously freak if they gave OOT the same treatment that Square Enix is giving FF7. I'm surprised WWHD and TPHD have not been ported yet. The Oracle games remade in the new LA artstyle would be perfect. Zelda 2 I think would benefit from a remake (the only Zelda I have not beaten).
Mario Galaxy 1 + 2
DKC trilogy, with an HD port of Returns.
I also would love compilations (I know, highly unlikely) of a lot of there older stuff.
