ShopDisney.com has revealed 3 new Star Wars TOYBOX Figures today. They are General Grievous, Imperial Stormtrooper, And Darth Vader. I believe the Darth Vader is just a repack, but would have to dig up my first release and check to confirm.
If you are interested in these, they are currently in stock at ShopDisney.com at the links below. These should also hit local stores as well.
