Show off the next Monolith game (assuming it's an RPG) and some kind of commitment to actually release it in the West in a decent amount of time.

That or show Western Mother fans some love in one way or another.

probably not. i'm not sure nintendo can or is willing to make games i want to play anymore.

Nintendo has to announce their best games like SSB4 and a new 3D Mario.That would be the best at the E3.I forgot a new Zelda game too.

When was the last time they made a game you really wanted to play?

If tomorrow's announcement is any good, they'll win me over for the whole year.

Just focus on games, games and more games. Microsoft could definitely learn from that. But more specifically i want a smash bros. game for both the wii u and 3ds, a F-zero (it's been 10 years since the last one!), and maybe a new Nintendo franchise.

Games, games, games. Preferrably, 3D Mario, Metroid, Donkey Kong, Star Fox, Zelda and something entirely new and exciting.

Nothing Nintendo related can win me over except for Zelda WiiU

Wii Sports sequel.
Zelda without any Aonuma influence what so ever.
2D Mario with production values and new content.
Smash Bros that is balanced, easy to play but as deep and melee.
3D Mario with focus on exploration, like SM 64.
New DKC by Retro.
New IP by Retro, or Miyamoto.
2D Sonic from Sega that is made like how I want it to be.
Pokemon, any platform.

Agree with you 100% there.

Though, I don´t see it happening anytime soon.
