A Star Fox with online multiplater in which teams of 4 friends commanding spaceships fight against other teams of 4 people.

Non off the ips listed for me just metroid zelda and a brand new fps ip I think

All of them. All the games.

I said Starfox (a Starfox Adventure like title would be great), but I also feel Metroid has been dormant as well (specifically 2D Metroid [better for 3DS though] and Metroid Prime).

Earthbound!

I want Nintendo to go back to The Mysterious Murasame Castle. I say they should, if they haven't already, gone to the team behind Red Steel (Ubisoft Paris), and have them develop the game in conjunction with whoever it was that made the Takamaru's Ninja Castle attraction in NintendoLand.

A combination of Wiimote swordplay and Upad/Wiimote Ninja Star gameplay would work well, I think (Use the Upad if you want the more "realistic" style, or use Wiimote either for off-screen play or to unify controls - point to target, press button to fix target, then flick wrist to throw it). Ninja Star sections would be on-rails, swordplay sections would use Nunchuk for movement control.

After that, I want Endless Ocean 3, Ice Climbers, and then 1080 Snowboarding. Both EO3 and 1080 would do well as games with optional Balance Board controls (in EO3's case, a full game borrowing controls from the diving mode in Wii Fit U would work great, but let players also play in a more relaxed style with more classic control schemes). Ice Climbers could be done a hundred different ways, but the way I'd most like to see is something that acts as a mix between platformer and a survival game (sans horror themes).

Amen to that

Well if I can't be greedy and say all.. then definitely Star Fox. Even if its just a digital-only eShop release, I don't mind as long as the quality is there.

100% star fox.

I think Nintendo needs to make a completely new IP, those are nice but a new one would be amazing.
