Its not by much but for all the bad publicity GB PS3 got for its toned down graphics (for god only know the reason) and the 8 million Difference in console install base...Outselling your competition by 2 grand is an accomplishment.
Though its not on the same scale as all of capcoms games on PS3 outselling thier 360 counterpart...its still a boost for the PS3.
...uhh...ill just put my favorite quote of all time here.
"Welcome to Pain, the second of three...You have dealt the first...now deal with me!!"
