That I agree  with, two tablets are fine.

10 person local multi player would be insane on one console. 6- 8 will be good enough.

Just a question... what the screen resolution of the Wii U controller?

That's some awesome crystal ball you've got there.

Well it depends, I'm sure some developers can come with great ideas for 10 players at the time, w/o being to hectic. It would be madness, but it can be awesome. 10 local multiplayer shooters maybe... 5 v 5? what about FIFA, 10 players in the same team, each controlling one player, while the keeper is on automatic? Imagine 10 people on Smash bros xD that would be just awesome! Of course u will need gigantic stages for that.....

I posted somewhere else that this could be a problem, just imagine an FPS on the Wii-u, i don´t know about any of you but i pictured glorious local multiplayer with each person playing on its own screen, making it a more fair experience ( you have to admit it, everyone looks at each others screen all the time on local mp ) and using the tv to display something else , like stats or maps or whatever they could come up.

But that would be impossible with only one tablet support per system, and don´t get me wrong, i´m excited as hell for this console but i´m worried that will be the case, and after all this talk about innovation...to what degree the consumer will be able to enjoy it?

i for one would be mad if me and my friends got together to play it and everybody gets stuck playing with just wii remotes, asimetrical play looks awesome and there are a lot of possibilities that could be explored, but as i said at the beginning of this post, they are limiting the experience, quite contradictory with what they are trying to sell.

854 x 480 (WVGA) This is estimate but a pretty good one

So it's not that huge... it's fine to stream this resolution in 30fps... the Bluetooth 2.0 could stream more than 2 controller at the same time.

Have a look at this gaf thread - http://www.neogaf.com/forum/showthread.php?t=433006 (Wii U gameplay ideas). Some of these ideas are single player, but some are multiplayer, and imo "revolutionary" (as in game changing) also for those that don't have the controller.

That said, being able to support 2 controllers would be better since it would open even more possibilities, and I hope that it does support 2. As to 4, while in theory even better than 2, I believe that once the price tag of a standalone WiiU controller is announced, nobody will bother getting that many... (i wouldn't be surprised if it's $100 a piece...).

First I would like to agree it will be a much harder sell than the Wii, not because the concept is not beneficial to casual games as well, but because it is not as easy to grasp in a second.

That said, beyond some things I can't imagine but they apparently plan to do with Wii Fit and other casual franchises, games such as Pictionary and Mario Paint say hi. Yes there's THQ's Udraw for the Wii, but

1. THQ's Udraw won't be getting any Nintendo made games, and only THQ will develop games for it (if at all) since not everybody has one

2. The ability of the WiiU screen to get completely different input and thus the player holding it be able to hide information from everybody else makes this a much better fit for games like Pictionary than the Udraw.

Now if you add to that the fact that all their WIi games will work on the WiiU and all the controllers they bought (including even the balance board) will work on the WiiU, and you have a nice upgrade path...

Reggie said WiiU supports 2 tablets. We can give the "only one" a rest now?
