This just in from the Blizzard press relations office:  Blizzard Entertainment and Valve have come to an agreement regarding the DOTA IP.  For months now a legal battle was waged, but Blizzard has relented, and will allow Valve to make their DOTA 2 product unhindered.  Blizzard DOTA will now be called Blizzard All-Stars, but any community use of the DOTA name will continue as long as it's not for commercial use.  

"Both Blizzard and Valve recognize that, at the end of the day, players just want to be able to play the games they're looking forward to, so we're happy to come to an agreement that helps both of us stay focused on that," said Rob Pardo, executive vice president of game design at Blizzard Entertainment. "As part of this agreement, we're going to be changing the name of Blizzard DOTA to Blizzard All-Stars, which ultimately better reflects the design of our game. We look forward to going into more detail on that at a later date."

"We're pleased that we could come to an agreement with Blizzard without drawing things out in a way that would benefit no one," said Gabe Newell, president and co-founder of Valve. "We both want to focus on the things our fans care about, creating and shipping great games for our communities."

I'm glad to see that Mommy and Daddy are now getting along again.  I hate it when they fight.
