Even though the 360 sells the most games in 1 region, still makes Microsoft last in sales atm worldwide (not game sales but overall). This will probably change when 360 makes its price cut (we know its coming) and Natal will maybe be a huge success but it can also be a flop. When this generation is over however, i do think that worldwide PS3 will have sold more units than 360, but 360 will have sold more in USA and more games. And most importantly made more money.
