Alright, you guys are getting me all excited about this TPM CG Yoda talk. I hope this is true. As for ESB and ROTJ, I think that Adywan is handling it perfectly, just CG his lips and his fake movements. CG is not nearly good enough yet for them to replace something so famous.

I just hope they don't replace the wonderful puppetry in Empire and Jedi. At least the Jabba puppet in Jedi would probably be too expensive and too difficult to replace completely with CG, so I think that's safe for the most part.

Lucasfilm definatly has the money. Even if they would release a new version of this film, it would make them a huge profit, way more than the money it would take to re-edit things.
