Dota 2 gets spectator client

Dota 2 as of today gets a free specator app for dota 2 today. You dont need Dota 2 in order to use it.
You'll be able to check out DOTA 2 matches from the perspective of players, or via a directed view of the match, complete with commentary. Eventually the spectator client will be rolled into the final game client ,once DOTA 2 officially launches. The spectator client is a standalone app for the time being.
