Just Microsoft trying to Monopolize gaming (as usual).
Competition is good for quality product. More competition you have, more developers trying to makes great games, more quality products you have to choose from. Consumers win!
If you really want a live example of this, Wrestling fans know the best quality of product came from back in the 90's when there was 3 Major wrestling organizations (WWF, WCW, ECW) now you got really one and their product is really lacking from the past.
BTW If this would have happened I don't think we would have had a Halo franchise. Instead Microsoft would have probably revamped Metroid to be like Halo, probbly would have killed Samus off... And made the new guy in her suit some jacked up muscle bound Arnold Schwarzenegger like freak. Just Saying.
