I'd like to believe, but....
I followed Spacedev closely for a long while when they supposedly were going to do a cheap asteroid exploration mission (NEAP). The BS was thick for a long time, but they kept postponing and postponing and postponing. Their credibility lost quite a bit with me over that one. I understand why they need to overhype their abilities in that it is a chicken and egg situation. Somehow, I don't think enough golden eggs are going to go Spacedev's way for them to ever have a chance to prove or disprove their claims.
