If you're getting it for the PS3 then you won't see me online sadly. I pre-ordered on Steam a few weeks ago, ironically after playing the PS3 demo.
I have to say that the PC Beta was more satisfying as well. Not just because I prefer a keyboard and mouse in FPS titles, but because the levels weren't capped at two and there were more unlocks than the console demo. Being able to call in Mortar strikes as a Sniper, or lay mines as an Engineer was very cool.
Overall the game seems quite well balanced and tons of fun. Much better than the demo of the first Bad Company I tried way back when it was about to come out.
