Yup, been with EP for 2 years, since Oct 2010. I grabbed 2M 4's, 2M 3's, 46M 2's, and 5M 1's. I scooped up tons of 2's in Feb 2011 after selling a profitable Big Board biotech stock. When EP went to no-bid, I felt really stupid. Imagine that feeling for over a year.
Yes, they are planning to file by the end of the year. So that means you have 2 months to load up.
