This is not the same sort of product Mark.

This product focuses upon maximum gpu performance, doing that in an  
older factory
makes you compete less.

The AMD CEO represents a public company. He can't just public say he  
won't be producing
his new stuff for the coming years in old factories and not be busy  
with new factories at all,
and then suddenly switch to a new factory for a new APU he produces.

That's basically not telling publicly the truth and gives investors  
and his share/stock holders wrong

Both AMD as well as intel always publicly shout about their TDP's,
yet in reality if we look what the box eats from the power tap, it's  
factors more
and it's not all psu losses. This where CPU is supposed to eat  
majority of power :)
