Or this is a brilliant cover up from Microsoft on a genuine leak. That is the fun with paranoia - there is always one more level of distrust.

Also specs of next gen devices are not that hard to guess.

Assuming goals are 1080p x 60FPS:

If you aim for sub 500 USD of production cost that retail at 350-400 there are not many balanced hardware solutions that could fit. My wild guess is that we will have 6GB of ram (it is dirt cheap so it makes no sense to have much less), because the invisible walls are something players and developers has complained a lot. 2GB of video ram and four core cpu. And maybe 7870/660ti class GPU and what is left of the budget for storage.
