Deathwatch RPG: by Fantasy Flight Games

Well the RPG is supposed to be out at GenCon which I believe is the first weekend of August. The first chapters have been announced, they are:
Space Wolves
Ultramarines
Dark Angles
Black Templars
Blood Angles
Storm Wardens

The last chapter is a fan-brewed chapter that came about through a contest. There is, at this time, no way to make a Space Marine from a chapter other than these 6, but I guess thats what updates are for.

I'm really looking forward to this.
