Kotaku's already shown 23 blissful minutes of lag-free Battlefield 3. The game looks realistic. It's like you're right there on the Caspian border. Know what's not realistic? Flying tanks. Oh, and spinning jeeps. Floating dudes, too.
The above clip is from the Caspian Border map. In what it lacks in lengthy, lag-free gaming, it more than makes up for it in what-the-f**ks.
Don't let this clip discourage you from picking up the game (EA can always patch things). Flying tanks and spinning jeeps aren't bugs, they're totally awesome features.
Thanks LulzJager for the tip! (And the lulz.)
