The Shogun - the CA Moderator at the .COM site - has posted the following at the TWC forums:

I did actually mention in a previous post over at, wwww.totalwarforums.com, that I would get back to you guys on this. I would like to remind you all this is the demo and it is not meant to fully represent full the game. I am waiting for the official line on this issue from the Oz office, which I should have by Monday. I did ask you all to be a little patient so we can get enough feedback from demo as possible and I would like that request to stand.

Cheers guys
Cryptic to be sure, but we should know on Monday how "representative" the demo is.
