ASICminer has 40nm coming,but we have no idea of hashrate & cost per miner....as of yet.I'm watching though
They look to be about .65-.80 watts per GH,MAYBE.so if they come up with a 250GH miner using 200 watts,it'll be a great thing!!! Watch for em!!!!!!!!!!!!

Asicminer chips will be 0.2-0.35w/gh and $1-0.5/gh
About twice the efficiency and half the price of anyone else.
Win win.
