On the SSG main page, there's a bunch of awesome new pics! Plus some serious SPOILERS!
A deluxe figure of Anakin that changes into Darth Vader - it looks like he has snap-on armor? It also seems that he has a cloth cloak, which looks a little big but may be the way he's packaged.
Unleashed Grievous - don't collect these, but he looks cool.
Lightsabers - Obi-Wan, Mace, and color-changing Vader. I couldn't tell if Obi-Wan's was from ROTS/ANH or if Mace's is the right hilt, but a color-changing one (finally!) will be cool, even if it is only from blue to red.
A 12" "Ultimate Villain" has Anakin, a burned face that I guess acts as a mask, and Vader armor. I probably won't get it unless the price is right.
April 2 seems so close yet so far away!
