On the Acusphere homepage it is listed as Q1 2014 also. It should be coming soon. 2 other companies listed on that link you posted filed around the same time Acusphere did. Last week 1 got a decision and the other has to answer some questions at a meeting.
The volume is still very low. There are only about 5mm O/S though. Even if you factor in the warrants Burrill have, which I believe are around 16mm, that is still only about 20mm shares. I think the warrants exercise at $1.20. So this has huge potential if they get approval.
