The International 10 Groups as well as the schedule has been released by Valve.
Two groups of nine teams each will play in a full round robin—two games against each opponent in the group—with a trip to the main stage hanging in the balance.
Four teams advance to the Winner's Bracket in the Main Event, while the others will have to battle it out in the Loser's Bracket.
Last ranked team in each group will be eliminated from the event at the end of the groupstage.
While the groups do appear to have been divided equally, one can't help but notice that Group A looks more deadly than Group B.
Simply put, Group A can aptly be termed as the "Group of Death".
The complete schedule can be found on Dota 2's website.
