There's news that Wave 4 of the Movie Heroes (SW) line might be at American retail by Christmas, but if not they'll be released in 2013 on slightly revamped green Yoda-style packaging to reflect next year's premiere of both Episodes II and III in 3-D.
Wave 4 contains the following new (or newish) figures:
Light-up saber Anakin (Episode III)
Sandtrooper (light-up cannon)
Battle Droid with blast-apart feature
