Wait until either Square Enix Presents or they announce pre-order bonuses for 2.5 If they don't say the Ultimania will be included, then you can talk about how it's unfair etc.
I'm almost positive SEP will be the place where they'll reveal the collector's edition stuff. That was one of the top three questions asked in the 2.5 survey. I have little faith that we'll be getting a 256 page KH history book along with our 2.5 copies, but we'll probably get something similar to the FFX/X-2 collector's edition, with a big hardcover artbook case along with the bluray disc music thing (which I know they're including with the Japanese editions, so there's a good chance of that coming stateside).
