Update: The update is now live for PlayStation 3 users in many European territories. We expect the patch to hit US users later today. If we hear from Sony, we’ll let you know.
If you’re encountering any strange in-game behavior immediately after applying the patch, don’t be alarmed — this is a normal function of the script backlog temporarily correcting itself. For more information on this, and how to speed up the process of PS3 performance enhancements, please read this forum post.
Original post: Following the PC patch, the 1.4 update for Skyrim is now live for Xbox 360 users. For the full list of changes, you can reference this blog post.
