If they have the ability to produce these chips on 55nm process (would think that they would have that ability by now) then economically, they absolutely positively must. There is no doubt that they will. Just when.

I also have to ask (apologies for being ignorant if they have) but have they produced any chip @ 55nm? There was also a rumor of 55nm 9800GT's with Hybrid power.....or all Hybrid power 9800GT's would be 55nm.......something to that effect. Don't recall seeing any of those.
