Not COS, POA. I'm satisfied with the official releases of the first 2 extended. Unless ADM added stuff that's not on the official DVD's? Well anyway, on POA, if you look at the international trailer there's a line cut from the Knight Bus that is something like this:
HARRY: Are you sure this is safe?
Stan: Don't worry, we haven't crashed in weeks!
And of course the bit in the deleted scenes section of the dvd from the Knight Bus (you can tell that it wasn't finished but still would be neat to have that added in (ABC doesn't even show that)
And the FULL tower scene with Pro McG. ADM missed a bit from that one scene. Other than that I can't think of anything else that was missing from that. Though I do hope you can finish Part 6 and maybe even do something with 7 part 1? I'm going on a trip and would love to have a nice little harry potter marathon on the way down before I go see the new movie. :) Sorry for the long post but let me know what you think. Going on my trip Monday so if you can't do anything with them I'll just settle with the regular editions. :)
