Rebelscum has some info
No figure reveals until NY Toy Fair.
Movie heroes wave 1 will have light up saber Anakin, sandtrooper, red exploding Battle Droid, Evolutions Jango (what, a good figure?), electronic R2, action feature Maul, spinning Yoda, light up saber Vader, and a terrible Obi-Wan. IIRC, we knew about those last year. (No packaged pics)
Anakin to Vader seems to be a 12" figure, which explains the high price point listed. The light up saber's color depends on if it's Anakin or Vader.
Some licensed products sport new "Vader reaching out"/ROTS package design. They'll mesh with your 2005 stuff.
