2 weeks?
Maybe a manufacturing/Packaging/Duplication issue. Unless of course it is Activision-Blizzard trying to increase console sales. I doubt 2 weeks is enough time to recall any discs allready duplicated, fix the "game breaking" bug then re-duplicate the game and ship it all over the world.
That would make no sense though as "per unit", I would suggest they make more profit from PC versions owing to the lack of a need to pay the console rights owner to "license" your game on their platform.
The game would allready have gone gold by now.
Surely they could still release it digitally on the original release date?
Another example of the retail channel ******* it up for everyone else.
