While everyone goes batshit crazy for the WiiU, which does look very interesting indeed, there was a couple of Warhammer 40k related game videos.
Dark Millenium Online. A touch brief this video :/
Not a bloody patch on last years E3 trailer for DMO mind you...
And Relic's single player console style Space Marine action game.
Oh and here's the WiiU controller advert thing. I like it, potential there.
