It looks like Titanfall is now being delayed by an additional 2 weeks. They just pushed it back to April 8th on 360.
Part of me says this is just a stunt to push more Xbones, but there's still a part of me that's concerned about this version of the game. First of all, tightening up things here and there doesn't make a lot of sense seeing as how this is a port. Anything minor that they mention could be handled in a post release patch. As it is, this game hasn't gone gold yet and it's 2 -3 weeks from market date.
