Personally, I don't think SEVU attracts many new investors. The only people who seem to pay much attention today are those who have been here for a while. I don't expect much movement until they report significant earnings, which may not be until the end of Q2. In the interim, a verifiable production announcement would likely help get some of the "old investors" back in, but there may not be much money there.
Of course a joint announcement with someone like Tandy (Radio Shack) would cause SEVU to appear on the PR list of a highly visible company. That would probably do wonders toward making the stock move.
