I'd pick one up if they started doing HD collections a la Mario All Stars.
SMB Collection (1,2,3, World) (Mario64, Sunshine)
Super Mario Land
Donkey Kong (DKC 1,2,3, DK64)
Sonic (1,2,3,CD) (Adventure1,2, {that team game})
Kirby
Star Fox
Kid Icarus (KI, Myths & Monsters)
Zelda (1,2,LtP),(Oot,MM,WW)
Mario Kart (SMK,MK64,DD,MKA) - w/ online play would be sweet
MARIO PARTY!!! - especially if it combines mini games (Change the first one's spin mechanics to motion controls for the love of all that is holy!) "You don't even want to hear the words 'Bash 'n' Cash'"
ETA: And I see there's already an HD remake or Wind Waker.
