The beta is supposed to come out for PC in December. I noticed when you look at the PS3's install of BC2 and look at information, it says 100 days left... until Feb. 2010. The demo is due early next year, most likely after the beta has ended.
If they are doing the beta like they did with BC on Xbox 360, there'll be a procedural unlock of everything. Right now when we play we have basic stuff and don't level up... with the upcoming days ahead, they'll unlock stuff where you can earn medals, exp, and unlock weapons and specials.

Played for an hour last night, got 6 different medals, leveled up to level6 and got a new sniper, pistol and shotgun.
It is weird playing an FPS on a console when used to playing it on PC. Wish you could force some AA.I have a excellent TV/setup and in the distance it just looks like crap. But overall a decent looking game and fun at that.
