@ Google: I agree; 4GB seems more plausible alright - but that would still be twice the RAM as WiiU supposedly has, wouldn't it? Perhaps it'll go to the integrated kinect the nextbox will have? As for your discussion about which card they'll use, I'm sure you're right - I don't have a clue :p
I'm on Twitter @DanneSandin!
Furthermore, I think VGChartz should add a "Like"-button.
