Andy responds: My understanding is that it's the Special Edition from 1997 with further modifications. The CG that was added in 1997 will be improved, since a few of them were really not that good (Han and Jabba in the dock, for example), and in a rare sign of listening to his fanbase, Han will shoot first again.
I hope there right. With improved CGI and Han shooting first it wil be a version made for me.
