I was forwarded a release schedule to take a look at, so I will just leave this up for people to discuss. I do believe that Imperial Guard will be the January release.
Please remember that these are rumors. Not sure what is up with the name the source wanted to be known as, but as long as there is no drama attached to it, it can stand. (new source)
