Well, we know assays are coming soon (next few weeks most likely). Robin said that himself in the video interview (find link a few posts back).
The sp moving is due to one of 3 things...
1) investors legitimately getting excited about the possibilities here. Spec is high.
2) a leak and someone knows something.
3) Someone is trying to make it look like one of the above is happening so that they can manufacture a frenzy and when results do come out they can dump hard.
I'm a pessimist.... so, I lean toward 3. But if it's not 3 then 1. I go with 2 last. But that would be my favourite. :-)
