According to CVG UK, all versions of Watch Dogs have been delayed until Spring 2014. I'll be interested to see some corroborating sources on this, but if true, this seems like a pretty big deal. Of course, if this makes for a better end product it'll be worth it in the long run, but we're so close to the game's release that I don't think many people were expecting this to happen.
In any case, there goes the one launch PS4 game I was particularly excited about. I wonder what sort of impact this might have on the new console launches, if any.
