i'm not against dark angels but no one else seems interested. I floated them some time ago and no one bit. Same with the new chapter and Imperial fists. Salamanders have 1 firm vote behind them and 2 other people say they are cool with them. 

And as for a new chapter, Well to be honest the first time I pitched this game like a year ago I picked a unknown chapter and it only seemed to turn people off so I expect what people really want something is cannon that is also well fleshed out so that they can research ideas. Even if they don't necessarily articulate that.
