The Defense of the Ancients Blog has an update from IceFrog, developer on this influential Warcraft III modification, saying he has joined Valve to lead a development team (thanks Ant via SK Gaming). Word is:

I have some really awesome news I'd like to share with you guys. I am now leading a team at Valve! I finally have all the resources needed to do some very exciting stuff that you guys will love. I look forward to revealing more specific details when the time is right.

My goal and top priority in the future is to solve the surrounding issues that affect the DotA experience in order to allow it to reach new heights. Addressing these issues will enable us to further enjoy aspects of DotA such as the gameplay, mechanics, and in-game feel that currently work well and ought to be maintained. As I've said many times in the past and especially after today's developments, I am very excited about DotA's future!
