What I'd love to see when they announce approval is a webcast the morning it's announced. I've seen other companies do it and it can be very effective if at the same time they discuss plans for moving forward. Often both the PR announcing approval and the webcast occur before the market open on a Monday, with both being announced over the weekend. In such a situation, European trading would be halted until trading in the US began, and it very well might be halted until the MM's could balance their orders.
I believe we could be getting first quarter results any day, let's see if any new guidance accompanies it.
