The rumor has it that it will be released this coming February, and that concept sketches have been seen. I wish we had a photo of these sketches.
The pic is from Dark Future Games by old school terminator. Nice Conversion.
Please remember that this is a rumor, and please take with salt.
I've heard from several sources now that the Void Raven is pencilled in for a February 2012 release. As always take with a grain of salt and don't get your hopes up.
MajorWesJansen, and no doubt others, certainly saw the concept sketches at Games Day Chicago, there were witnesses.
