They need to give Zelda, Metroid, Mario and Pokemon a rest for a while.
They have so many games and franchises under their belt, they need to widen their library. Bring back Mach Rider, make a new Punch-Out, make a solid sequel to Geist (so they can get the FPS fans on-board) and revive Project HAMMER. Make a sequel to Pikmin, a new Excite Bike and/or Wave Race, a new Pilotwings (come on, this is a no-brainer for the Wii), and a revival of Kid Icarus. Hell, a new Hogan's Alley is a no-brainer for a WiiWare rails shooter title.
Oh, and revive Mother/Earthbound in one way or another. DS collection, Virtual Console, Wii collection, new title in the series, I don't care. They need that franchise to return.
No more Zelda for a while. No more of the "Big Four" (Mario, Zelda, Metroid, Pokemon) for a while. They've been milking a few of these franchises far too much in the past couple years. It diminishes the value of new games in those franchises, and lowers variety and creativity.
