I think it'd be neat to have a desert/wasteland map.  It's the sort of "traditional" 40k battlefield--some sort of blasted landscape with little vegetation and plenty of open spaces.  It'd be simple, but that's not necessarily a bad thing. 

I've known about this since September.  Although it's still very exciting. 

Although, despite being an Ultramarines fan, I have to say it kind of bugs me the way they always steal the show.  Hopefully, if this does well, we'll get a sequel film relating to Eldar or Necrons. 

Maybe this movie will be about the Marines holding off the hive fleet, which would be awesome.  Hopefully it won't just be an utterly generic "marines vs Chaos" or "marines vs Orks" scenario.
