You do realise that the 360 is about 9 years old right? 9-year old hardware does have limitations, y'know and if they want awesome new games, they're gonna need new hardware to work on. If they were to work on the 360 for the rest of their lives, then games wouldn't innovate anymore, they'd be all the same. Also, by your logic we didn't need any of those other consoles either, all we ever needed was the Magnavox Odyssey and other Pong systems.
