I wish they announce a remake of Kirby 64 with improved gameplay and extra content (story, levels, playable characters and extra stuff)...
They remade all the classic games (counting Spring Breeze as a Dream Land 1 remake) except for the Dark Matter trilogy, it's time to remake one of those as well, they're classics too; especially Kirby 64 that can get rid of the hardware limitation of the N64 and be improved in both gameplay and visuals.
I say this at each big event or before every direct, but so far it didn't happen yet.
Though, I wanted a remake of Majora's Mask too and some years ago it arrived on 3DS (even though it wasn't much different than the original), so I'm sure that something similar can happen with Kirby 64 as well sooner or later.
