And the RV770 (on 55nm) consumed between 110w and 190w of power, but that was determined only by the core speed (525 Mhz being the lowest and 850 Mhz the highest), being unrelated to the number of available shader processors.

The power is not a problem because that new GPU will be make in 32nm...

How do you know? Do you know how many 32nm fabs are actually operating (you qould be surprised) for mass manufacturing? If they really had a 32nm line, wouldn't they shrink the CPU first?

Let's not forget the 4890 is an RV790 chip, not an RV770 chip. Even at 45nm, we are looking at TDPs of >100Watts, and adding the rumour of a superfast CPU with a TDP over 125-150Watts, that would make a hell of a lot of heat to dissipate for such a small WiiU box as shown in pix (I love the picture where a Ninty guy places the WiiU into an almost completely enclosed TV stand.. that unit would melt within minutes..)
