Now both on 0.93mil.
Still, PS3 tie ratio is better than 360's.
I tend to entertain the thought that PS3 fans are bigger on thriller/action/adventure games than 360 fans, who are bigger for shooters. PS3 sold more with Prince of Persia despite (I think) it having 360 advertising in the UK, and more with Tomb Raider (although that was traditionally a PS franchise, so not quite as valid an example to support my theory).
