Interesting. I just picked up the reproduced version of Pearl Jam "Ten". That wasn't so much remastered, as they took the main tapes and completely redid the production w/Brendan O'Brien. It's a big change imo, and a good one too. Ten has always sounded very dated (especially compared to the rest of their work) from a production standpoint, and much too "slick". It rocks much harder now. It also has 6 unrealeased songs including Brother (which ******* rocks face), Breath, and State of Love and Trust. Previoulsy unreleased MTV Unplugged DVD too. Worth it, imo.
Hopefully the Beatles come out good as well. I would pick up a remastered Abbey Road.
