Either do you. Didnt you read the bit that said "Lets say Nintendo sells the Revolution.."?, ie, its a hypothetical situation.
I pulled the $200 USD figure from what the competition is spending/losing. Sony is forking out something like $100 per item (BR, RSX, CELL) so I thought I'd use the same figure for the Revolution.
The only 100% true thing we know is that IF these specifications are indeed correct, there is no way in hell Nintendo can sell it and make a profit from each console sold. From previous discussions from the media, we've heard from Nintendo's mouth that they plan to make another console that is profitable, afterall, a profitable console is the only thing keeping them afloat in the console wars. This kind of renders this rumour false.
(Not to mention the tons of inaccuracies in the actual specs, eg, how can a IBM PowerPC 2.5Ghz produce better performance then a IBM PowerPC 3.2Ghz with three cores? Another example is the insane resolution and the hella expensive RAM/PPU)
Nintendo, If these are indeed the official stats suprise me and sell it under $500.
