Well, it just seems Square Enix is delaying all their games today as the Crystal Dynamics developed Marvel's Avengers has also been pushed back. Originally slated for a May 15th release, the game will now be releasing on September 4th. Crystal Dynamics has released the following statement regarding the delay.
I have personally been on the fence about the Avengers game since it's announcement back at E3 last year. The story seemed enjoyable but the revealed gameplay really left a lot to be desired. Hopefully, with this delay, the game will live up to the standards Crystal Dynamics has set for their titles.
