here's what I think. I think they will announce how they used the funds of the last secondary over the next two weeks. which I expect they bought 450k more facebook shares and then after that. It will be around the 30 day N-2 Filling periond they will do their secondary so that puts it like this. Pop for next two weeks drop in late April early May. Pop middle of May before and during Facebook's May 17 or May 24th list.
