actually if u use brain,logic,eyes....ey sell on par(only fanboys refuse to accept this),maybe with slight edge for 360 since its longer on market with more games.we all know gt5 ll sell on halo level,mgs4 is over 5 mills,gt prologue at 4.6 mills(official reports).
we dont know where ll uc2 end,big chance 4-5 millions after price cut and bundling,here in eu that game is still at high price 30-40 pounds 7 months after release.
so i d give slight edge to 360 but nothing big as u want to represent it.
