It'll be interesting to see what the Emperor figure is in this wave. We still sort of need an "ultimate" Original Trilogy Emperor figure (the Evolutions/Order 66 pack based one is on the right track), but it doesn't really fit into an ESB wave. Otherwise, the rest of the wave looks pretty good to me. The Luke and Leia are likely the long rumored and requested "Medical Frigate" figures, and Captain Needa is a nice addition as well. The Ugnaughts are a needed re-do, and could be pretty spiffy. The big figure of this wave, to me, is the Hoth Rebel Trooper. We've all been waiting for them to go all out on the Rebel Troops (this one in particular), and hopefully they'll knock it out of the park. With there not being an "action oriented" version of a main character in this wave (Luke and Leia are more of background/dressing characters in these outfits), the Hoth Rebel Troop is sort of the anchor of this wave.
Like it was mentioned, I do hope we see that ultimate Bespin Han (and/or Hoth Luke/Leia) in the 2nd Empire wave for 2009. With this wave, and the 2nd including Willrow Hood, it could shape up to be a great year for Empire figures.
