So interestingly it seems as though Neogaf users in the know are now quite openly talking about the Wii U. One of the insiders there has been talking about how the RAM has been bumped up. Going from 1.5GB to 2GB total.

Honestly that is fantastic news and is really the absolute best situation that could reasonably have been expected.

So at the moment there is 1.5GB available for games. A pretty nice 3 times of that in the 360. With an extra 512mb currently locked away but potentially some of it becoming available.

Assuming the other parts were in line with it then it would be a very nice bump over the 360/PS3.

If you look at my next gen specs thread it has 512 XDR ram and 1GB of video ram. I'm now thinking they bumped up the regular ram and left the XDR ram for the OS to make sure the system, its tablet, and all the new Android based features run flawless while still having a large enough storage of additional ram to make games still superb.

Yup most likely. Could you link me to your next gen thread? 
Also if you need a source for the increased RAM then on this page  http://www.neogaf.com/forum/showthread.php?t=472816&page=387  bgassassin is known as someone with inside knowledge and confirms the 2GB.
