After a few delays, the first (and hopefully not only) case featuring Wedge Antilles and Yoda has been posted to Entertainment Earth.  It's a Wave 3 revision, so it also sports the Gamorrean Guard, Jedi Luke Skywalker, R2-D2, and other really awesome figures from last year.  Pre-orders are open now and, as always, we'll have more information as it becomes available.  For now this is the only known case with Wedge.
