Yeah, I saw that article and that news is very promising. Personally, Star Wars would make just as much money as a 2D release.
Now, It sounds like Lucas will be adding more changes, which for me, is always fun to try and spot them, no matter how I feel about them.
My hope, is that only a re-vamped OT makes it to the screen. I don't want people who have never seen Star Wars to go and see TPM or AOTC cause they'd give right back up on it. Also, seeing a movie with bad CGI would be terrible in 3D. Especially Jar-Jar.
I really have no clue what Lucas may have in store for this. New shot scenes from when the PT was filmed? New soundtrack? Deleted Scenes added? A re-vamped Obi-Wan and DV duel?
