They will just use the Wii controllers for that. The WiiU tablet probably will be too expensive ($80-90 is what I suspect unless good resolution 6.1inch touch screens suddenly are available for free next year) to buy 3 additional ones for some WiiU party nights, but I think they should be able to support at least 2 at a time for fleshed out 2 player Co-op.

Whoever gave Nintendo's E3 less than 7/10 is crazier than I am. Or just dumb. Me, I gave it a 9/10. Smash Bros. on the 3DS is perfectly logical, given that it's the first and presently only handheld with reliable analog controls. And it'll probably remain that way even after the PSVita is released. Yeah, that's right Sony: I just called you out on your history of bad analog control with handhelds. Bet you wish you could have come up with the Circle Pad, but you can't, because your creative minds are inferior to Nintendo's creative minds, in every possible way. You didn't think 3D had a place on a handheld, history's gonna prove you wrong. Oh, but you have a touch pad on the back of your handheld? How the hell can anyone use that outside of editing?! And you just had to rip off our touchscreen, didn't you? Oh, but yours has a higher resolution than ours. Our 3D screen has a higher resolution than your touchscreen and is capable of 720p  (or i, I don't remember which). Yours has a camera? Ours has three.  Yours has a microphone? Shit, dude: the original DS had a microphone, and all of our handhelds since have included one. So, I'm done comparing penis sizes. I'm done with this rant. Vita and Halo 4 be damned, Nintendo won E3!

8/10 for me and the best this year, although it could've been much better.

Nintendo should have announced some more Wii games (where the hell was Pikmin 3?!?!??} and some first party games for WiiU

8/10

Yea, I was actually just thinking about just using the Wii controllers for 4 player multiplayer myself considering that it is backward compatible.  I don't really see anything beyond mainly a 2 player focus for the tablet controllers due to price contraints for most people.

Ninja Gaiden 3 is not exclusive.

3DS: 10/10: Luigi's Mansion!!!! FUCK YEAH!!!!

Wii is dead: 0/10

WiiU?

8/10.

-1 for less Wii games.
-1 for being to vague about their new system.

3DS part made me :D X 9999999

I give'em an 8. Hardly anything for the Wii and DS owner. And i wasn't clear and still not convinced on WiiU. Looks like 3DS will get better later in the year.
