Luigi's Mansion 2 is actually pretty likely IMO (The Revo trailer had two people looking around in the dark in a very Luigi's Mansion style)
My Wishlist
1, A new Waverace developed by EAD (Please Nintendo don't let those hacks at NST get their hands on the Waverace licence again!)
2, A new Starfox game made by EAD (After the last two abysmal games, I can safely say that EAD are the only ones who can do it!)
3, Wario Ware Revolution (Come on you know it's gonna happen!)
4, Pilotwings Revolution (It's been rumoured for ages now)
5, A 2D Advance Wars game (With online gameplay!)
6, Fire Emblem revolution (Probably best in 3D)
7, Panel De Pon revolution (with online gameplay and the original fairy characters!)
8, A sequel to Kirby's Dream Course
9, A new 2D sidescrolling Metroid!
10, NiGHTS revolution (I know it'll never happen but you've gotta dream!)
That's all I can think of at the mo...
