Obviously someone who thinks it will go still lower, or a shorty.
Some get scared at the filing delay, and depending on the reasons for it, they may or may not be glad they sold.
For any stock/company, the way it is run is at least as important as the "widget" they sell.
We have yet to really see any sales figures, and the company so far has not demonstrated enough that it is a properly run company.
This is not bashing by any means, but you do have to look at all facets of any business you invest in(sales,profit margins,cash flow,debt,demand for product,competition,etc. etc.)
By the above I just think there is still alot of uncertainty for potential investors.
Seeing some sales figures will help to clear up alot.
