This very exciting if you're a PS3 owner. I can imagine GG is all over this tech right now - considering their obsession with round edges. I hope this will lead to the end of Quincunx on PS3. I kind of figured it was only a matter of time before someone figured out how to use the cell to do AA.

I doubt Guerilla Games is all over this, KZ2 AA was amazing, GG steps on Pandemic's face, eats it, shits the face out, and eats it again the next morning for breakfast.

What technique does GG use, do you happen to know?
