Where can I find news on Skyrim's updates and patches for the Xbox 360?
Any info helps, thanks.

For info on Skyrim and other Bethesda-related content, visit http://www.bethblog.com/

The blog is the best site for updates, all major news items get posted there. A lot gets posted on the forums as well but you need to be willing to look for it - and often any additional information or updates are quite minor. The blog really is the best place for solid and organized news.

There are also FB pages and twitter feeds if you want to investigate them.
