They won't do p2pool.
They only need to point one 10GH/s board at it and they'll see the current problems with p2pool.
Then imagine 8TH/s ...
Read the p2pool thread for more details.
Still spreading FUD around? I've used p2pool with more than 10GH/s for months and didn't have any problem with it. Unless ASICMINER tests p2pool (probably using a stratum proxy) there's no way to know if it will or won't work well with their hardware.
