Hey, I got an artbook today! I never preordered, but there's an EB store 5 minutes from campus, so I figured, what the hell, I'll see if they'll give me a copy. I get there and ask, and sure enough, the guy working at the counter opened a drawer and handed me one. I saw they had a large stack of them, so I didn't screw anyone out of their preorder bonus.
Anyway, the artbook is really nice. It has basically the same dimensions as a comic book, and the cover has a sort of 3D effect, raised areas makes it look like it T-elos is coming off the cover. It's a very nice bonus, a lot better than the Suikoden V artbook. Though, that did include a CD, but comparing the actual artbooks, the Xenosaga III one is much better.
Anyway, if you didn't preorder, just ask. The CSR that waited on me was actually one of the nicest ones I've ever talked to in any EB/GS store.
Good luck!
And yeah, I read about the blood in some scenes of the game being edited out, yet the scene itself remains intact. It sounds pretty lame. But I'm going to play the game before I start bitching and moaning about it.
