why not make monster enrgy and rockstar energy skins and sponsors for the bikes

since so many people like rockstar energy dirt bikes and monster energy dirt bikes why not make a new game add on or just add it to the game as sponsors, skins, helmets, gear, i know this will sell on xbox live i know i would buy it and maybe throw in like the training tracks for the two sponsors monster energy kawasaki training track and rockstar makita suzuki training track, just a few thoughts but these are the two big sponsors and alot of people like them and im sure they would like to have them on the game and the racks because not that many games do the actual training tracks so that would be different and people would like it i think....
