This may come as a shock to a lot of you, but "Team Deathmatch" in Battlefield 3 will only support up to 24 players, no matter what platform you're playing it on. Yes, that even means you, expensive PC rig. Don't get yourself into too much of a rut, though, because the maps are more condensed than their Rush/Conquest brethren, even ditching vehicular warfare and only focusing on tight gunplay.
Thinking back, this may not even matter to a lot of you, including me, as we'll more often than not be capturing flags and destroying crates.
