Over at the EA Play site one of the admins has posted a little bit of information about the demo, check it out:

Although final dates for the Battlefield 2 demo have not been locked down we understand we will be allowed to make it available in little over a week.

Once again these features are not 100% final but the demo will contain:

One map
16-player single player
16 and 32-player multiplayer
Time limit per round

Other information we have received is that the testing of the demo finishes tomorrow, so could be released as early as Monday. Judging by EA's tendency to release stuff on Friday though, clear your schedule for the 10th. Read it for yourself here.
