One quick 'rumor squashing' comment: A few news sites seem to be reporting that Battlefield Heroes(tm) will not be available in Australia. This is most certainly not the case. Battlefield Heroes(tm) is available as a free download from the web, and as such would probably be available even if you connect to the internet via a satellite dish from a small unheated hut on the steppes of Uzbekistan.

General Information:
. 2 Armies: National Army vs. Royal Army, All stereotypes used for comic look
. At release, 2-3 maps with more rolled out in updates
. Pick one character and you level him up through the game
. Maps do not have insertion points, and the game chooses where to put you on the battlefield, although maps are a lot smaller than regular Battlefield maps
. Known Weapons: Sticky Bombs, Rocket Launcher
. Taunts and death-freeze-cam included

Modified Conquest Mode:
. At the start of each round each team has 2 flags and 100 tickets
. Killing enemies reduce tickets, but if you hold more flags then your enemy you receive a multiplier giving you more tickets
. You can win even by killing less enemies and owning more flags
. Killing enemies is less important than capturing and holding flags

Vehicles:
. Observed vehicles: Spitfire, M4 Sherman, PzKfzIV
. The character size relative to the vehicle differs quite a bit. Comparable to "an adult on a bobby car"
. Planes have no bombs, used mainly for dogfights

Abilities:
. "I Eat Grenades" Ability - Throw back 7 grenades at once
. Life-Points Boost
. Inflammable Ammo

Match Making:
. Play with level equal players, but not 1:1 Ex: Level 2s could play on a level 1 server. Rule seems to be "level X ±"
