Well... I guess Wave 3 isn't a rumor any longer thanks to the Star Wars Celebration reveals.
So may as well start a dedicated discussion thread for that wave as well.
The wave consists of Luke: Bespin, Stormtrooper, and Obi-Wan: RotS.
You can find some pretty good Hi-Res pics here:
The 4th figure in the wave is supposed to be Anakin: RotS to pair with the Obi-Wan: RotS.
Luke's face looks a bit wonky in the badly posed Hi-Res pic. But pretty darn good on display at Celebration.
