According to NeoGAF, that is...

CONFIRMED By an unofficial resource.

That's like saying it's Christmas in July.

Who said it ideaman? He's a pretty credible source

Um, yeah, no.

This is by no means "confirmed"

Moving on...

GAF is usually a pretty reliable source.
But yeah, that person shouldn't be yelling "confirmed" already.

That's...cool? How many will support it though? How many will want to buy a second tablet even? I'm still surprised demand for second tablet support was so high in the first place. As if $60 controllers weren't bad enough...

Reggie said this months ago, didn't he?

No, Neogaf has been wrong quite a few times too

WiiU should be able to support two controllers at least... Even use 3DS as a controller too- though, most likely with Circle Pad Pro since with it since it has all the inputs the WiiU tablet has

Darn those Nintendo fanboys into tricking me!

Yeah but every source has bad days. For the most part when they aren't hating everything gag is pretty credible.

Honestly what difference would a second tablet make? I personally think this is being overblown

I would have been glad to hear this last year but not anymore. Now I'm thinking the devs will just end up ignoring the old Wii Remote Plus controls when making new games.

I think multiple tablets - cost aside for a moment - would be a good idea. The ideas that have been thrown around before, where 1 person has their own screen that no-one else can see, would get exponentially better with more screens (assuming game devs can use it well). Having more options like that can result in better games.

However, there's always the problem of fracturing the userbase. If a multiplayer game requires more than one tablet, that's asking for trouble - especially if they cost a small fortune each.

I'll wait till E3, thank you very much.

I do believe this would make for six-person local multiplayer, as it has already been stated that four Wiimotes can be connected as well as the tablet:2 players with their own screens, 4 players splitscreen on the tv with the Wiimotes.

And would the WiiU have enough power to generate streamed video for two tablets and still be able to work on HD in TV?

I'd like to see four of these controller hooked up to a single system. There's a lot of ideas that could be utilized for that. It would help out with multiplayer RPG's a lot. It could be used for another Four Swords game and even allow Four Swords Adventure and Final Fantasy Crystal Chronicles to work on the Wii U. Each player in a first person shooter could have all their info right their on their screen, taking all the HUD off the tv. When players need to select something (like a play in a football game) that they don't want the other players to see they can have their own screen. For a card game, each player could look at their own hand without anyone else seeing. And the ideas could go on.
I noticed people concerned about whether the Wii U could handle so many screens at once, but in most of my scenarios, the controller screen would only really be used for menus which I would think wouldn't be that hard for the Wii U to handle. But, I'm no expert.

When the day comes, that my friends and I could be holding our own Wii u tablets, playing them, together, on the same console, then I will be jumping in glee.
