The delay includes all versions, per the following statement from the Watch Dogs team:
“Our ambition from the start with Watch_Dogs has been to deliver something that embodies what we wanted to see in the next-generation of gaming. It is with this in mind that we’ve made the tough decision to delay the release until Spring 2014.
Much respect to Ubi for delaying it instead of just releasing it broken or unfinished. I have plenty of free to plays to play on my PS4 until then anyway :)
