The world of professional Dota is about to get a lot busier. Valve have just announced the Dota Major Championships, an annual series of 'marquee' tournaments that will include their established The International event. The other three shindigs, they say, "will be Valve-sponsored events hosted by third-party organizers at different locations around the world".
As you can see in the above picture, there will be an event in each season, starting in Fall/Autumn and culminating in a bigger event, presumably The International, in Summer. The first is scheduled for this Fall/Autumn, and Valve say they'll reveal more details as that draws nearer.
Next week, Dota 2 will receive a "major balance update", along with this year's version of The International Compendium.
