If anybody cares, they've opened up BF:H for open beta. You can sign up here if you interested: http://www.battlefield-heroes.com/
EDIT: Looks like it's not entirely "Open" beta persay, but still they're giving out a bunch of keys and downloads. Good Luck all non-the-less.
You can sign up for the Beta at the home site: www.battlefield-heroes.com
, or one of the "sister" forums.
The Beta is in it's final stages as of 4/16/09, and should be live by the end of April into mid May. (they haven't decided yet because of how many bugs and other little things there still are to fix) As it being in the final beta stage any and all characters you create now will be rolled into the full version when it's released.
-As of 4/16/09 the things you buy in the Battlefield Store are only temporary purchases, and in order to get BattlePoints you have to add them using a Credit Card (The addition of PayPal will be added soon according to James Salt)
-As of 4/4/09 Dice/EA has turned off PunkBuster in the Beta because it is keeping people from joining servers, and other miscellaneous issues. So there are a bunch of scrubs who are hacking, but they are being caught by screenshots and being Temp IP banned until the full game is released. (according to the beta forums)
Good luck to those trying to get in, and to those already in I'll pwn your scrub *****!
