I work at a game store and it came with some 3.5 promo stuff that we got a week or so ago. They just gave it to me. I figured up till now that it was coming with the books, or at least the store would get more to hand out to people.
Bad quality actually. ALSO it actually says that there are too many changes to list in the compatibility guide. So most larger issues are mentioned but apparently not everything. I have yet to compare the two versions for an elite comparison.
Just wait til the 18th and hopefully WotC will have a nice copy to download or maybe our FLGS's will have a nice copy handy... though it seems not by what posters above have said.
