After yesterday's deluge of information concerning Warhammer 40,000: Dark Millennium Online, THQ has flatly denied that anything we know is true. That includes class info, studios involved, and the March 2013 launch window.
"It has come to THQ’s attention that some media are reporting that we’ve announced game details and a release date for our upcoming Massively Multiplayer Online project, Warhammer 40,000: Dark Millennium Online," stated the company. "At this time THQ has not officially announced a release date and any reported features are pure speculation. THQ will announce confirmed game features and an official release date at a later time."
Well there you go. Of course, with THQ already confirming that it's invested in Warhammer 40K and that Space Marine may not get a sequel thanks to this MMO, one can be sure that not all those details were false, especially the combat part which THQ's own Danny Bilson appeared to confirm earlier today.
