Along with the recent Kinect patch released on May 1st, Bethesda has released a teaser for the the first DLC expansion for Skyrim through their official facebook page.
Although no offical information has been released about the expansion, aside from more information to be released at E3, users sneaking around the game's data files on the PC have seen hints that there may be Snow Elves added and Crossbows (is that featured on the poster?) may make an appearance also. Even those users snooping through the files will have to wait for the official release of the expansion, titled Dawnguard, because Bethesda has announced that all expansions will be exclusive to Xbox 360 for the first 30 days of release.
For those who are just getting adjusted to speaking to the world of Skyrim through Kinect, Bethesda has released a list of commands to let players know what they can do with the new functionality.
