Out of curiosity, I thumbed through a copy of the Official Guide at the bookstore a couple weeks ago. I figured that WDW would at least clue their "Official" guidebook team on to the drastic changes coming in 2005.
Nope, the Birnbaum books still reference the "old" tickets and packages. Seems like a foolish move on their part, since if you purchase something slugged as "OFFICIAL GUIDE" you excpet it to be at least factually accurate (with a side of bias and rose-tinting).
It would seem to me that Disney could have had the books printed with all the new 2005 programs included, but placed a moratorium on selling them until the press release date of December 2.
As far as which guide book actually left the bookstore with me, it was the Unofficial guide.
