They're trying to be more efficient this time.

Do they support 3D? :o

The Gamecube supported 3D, but the feature was never enabled because nobody wanted it. Luigi's Mansion was even developed with 3D in mind.

Assuming it's a traditional console and not something else like a VR machine then:

A quad core ~3.5 GHz CPU based on the latest Power PC tech

1 Gig Ram

GPU capable of 1080p output

16 GB or more internal storage

Full backwards compatability with Wii and GC, including controller ports.

WM with Vitality Sensor built in (no finger clamp deal, just hold the controller and it knows)

That'd make it noticably more powerful than PS3/360 yet not a whole lot more expensive.  It's very likely that'd cost less than $300 to build today.

I just want good games and an online infastructure on the level of PSN/LIVE

you guys are all going about it backwards. this is Nintendo, not Sony.

Lets assume it'll cost about $300, okay? that means It'll have the best PC $150 can buy at time of launch (cost to manufacturer, of course), and an additional $100 of desruptive features that nobody else has done yet. That leaves $50 for profit split between Nintendo, shipping companies and retailers.

Now go figure out the specs of the machine...

edit: this machine here is $300 (cost to consumer) as of now. Profit margins are probably slim, but it's reasonable to assume it'll be around $150 to manufacture by holiday 2012-spring 2013.

I won't bother with specs but more powerful, HD, '3D ready' more internal storage and much improved online are all musts. Unified friendcode.

Enhanced motion controls - WM (without constant recalibration) on both wii2mote and nunchuk.  Sure add camera. Add an embedded analog stick to the wiimote (similar to the one on the 3DS).   Better mic.

Backwards compatible with Wii, but I can't see GC.  Why bother with adding the controller and memory card ports?  It's becoming harder and harder to find GC games as it is.   Move GC to VC.

Channels are fine but much more streamlined and 'push' material to users (especially casuals), especially WW,VC, Demos, etc.    I'm amazed how many people don't even know about Wiiware/VC and especially demos.

Maybe do a simplified, Nintendo style,  mii-ifed version of Sony's Home in the Mii Channel.

More ingrained with social media.   Connect to Facebook/Youtube/etc.  IE: Post game achievements to Facebook, SSBBrawl2 fights to Youtube - direct from games.   This could potentially go much further.

The real question is what will be the new twist Nintendo adds?   DS had touch screen, Wii had motion controls, 3DS has 3D.   So what will Wii2 bring to make it revolutionary and more accessible?  Beats me.

Honestly, I just want it to have equal or better graphical ability to the PS3/360 and come with a traditional controller with the option of a motion controller to buy later.  After that, I don't really care, because I know Nintnedo is going to come up with something none of us can predict.

Stuff all the specs in there while keeping it to $299.99.

For an extra $50 on the $250 launch price, they can put "future-proof" stuff in there for those voracious 3rd parties who need 'power'.......

Full backwards compatibility with the Wii, with Dolphin-like upscaler (or whatever it is called) that displays Wii games in full HD. (so also capabaility for Full HD built in of course).

Strong enough to play 3D games.

Size limit on Wiiware removed so whether a game is digital distribution or retail is a matter of choice for the developer.

Full, transparent communications with the 3DS, with the ability to start a game on the home console, continue on the 3DS, and then when back home continue where you stopped (with the 3DS) back on the console.

Ability to usethe 3DS as a sort of tablet controller for the console.

Add a camera peripheral to the controls to complemennt but don't dump the controller.
