Some info on the Jedi Council from the Set Diaries. The council no longer has it's polished look, there are scruff marks along the seams, and the chairs have slight abrasions.
The call sheet says that Anakin enters the Jedi Council but it's also told to us that Obi-Wan is required for the scene? Does he enter with Anakin, is he already there, or is he on the council???
Other returning characters in the scene is Mac Windu, Ki-Adi-Mundi, Plo Koon, Stass Allie, Saesee Tiin, and either Agen Kolar or Eeth Koth (he was named Agen Kolar on the call sheet, but they're still unsure if it meant Eeth). Yoda will be there in his CGI "glory" .
Ki-Adi and and Plo are actually not present in the movie, they're off on a mission somewhere, and the are represented in the council via hologram, which sounds pretty cool .
There will be some changes to the council, and Rob Coleman is trying to get Trebor's son on the council.
