While its good news for xbox fans who dont mind buying yet another machine,it does not mean that mgs4 will be out for the system,nor any other game based on the bluray format,just as they didnt release any on hd-dvd, they couldnt ship games that only a small percentage of players could actually run,all we will see in this generation of xbox,will be movie functionallity, but now they have the technology,it will be in the next xbox branded console from day one.
