Personal Spaceflight takes note of a Bigelow Aerospace information release promising big news on April 9 at the Space Symposium and speculates that it might be about the company's Sundancer spacecraft. Googling the spacecraft turns up a brief mention on Gunter's Space Pages - and not much else.
I recommend Personal spaceflight if you have an interest in private space initiatives. Take the feed.
[Update:] Alan Boyle at Cosmic Log has much, much more on Bigelow's vision and the performance of its Genesis module, already in orbit.
