They'll all be working on this and probably have been for many years, if you read the right stuff you'll see the odd comment about plans for 22nm which is 7+ years away.
I can remember reading about IBM experimenting with 65nm while Commodore were still around, but only at the lab level.
Freescale (and partners) announcing a while back they'll be going into pilot production in under a year.
Considering they haven't properly 'broken through' with 90nm technology*, I'm skeptical.
Intel will be using SOI for 65nm so their leakage problems should reduce considerably.
