The only thing I really want is a remastered TPM. The transfer on that DVD is horrible and nowhere near as clean as AOTC and, presumably, ROTS.

I also think the ESB puppet Yoda is the most believable Yoda, but a CGI Yoda in TPM would be more consistent with AOTC and ROTS.

I'm hesitant to buy any Star Wars box sets, new content or not, due to the impending release of BluRay and HD-DVD. Lucas took his time with the DVD release of the OT so he could do some more work, but I think the HD releases will hit the market much sooner.
