Graphics are only important to a certain point.
When you first play a game, you may say "ooooh...pretty graphics". After a while, it is immersion and gameplay that takes over and makes the game fun. Graphics may help with the immersion, but if the gameplay sucks then you won't want to play the game for very long.
What I am saying is, get over it. If the graphics are slightly worse because it is being made for the XBOX360, it will only ruin it for the people who care about that sort of thing.
