Anyone know if all four of these are official in the running? Any others?

Clockwise from upper-left: SpaceX Dragon, Blue Origin New Shepard, Boeing CST-100 and Sierra Nevada Dream Chaser.

I don't know, but if I was a betting man... I would say it's probably the Boeing CST-100. I've seen lots of photos of it, and it looks similar to our Space Shuttle vs. the cone shaped ships that we used in the 60s.

***Correction***

I meant the Sierra Nevada Dream Chaser. This bad boy.

I don't think that Blue Origin is in the running, but I could be wrong.

I'm hoping that that they go with a full share for SpaceX, with a 1/2 share for the SNC Dreamchaser. SNC is in a unique situation, since they have some agreements with ESA to help in their development.
