This year the brackets are hosted on the challonge.com website.
The official brackets of ATXVI are here. The bracket has been seeded by CCP based on the results of last year as calculated for previous tournaments and new teams (with no seeding from ATXV) randomly positioned. This will be updated as the tournament progresses. You can also create an account to make predictions on the upcoming matches if you wish!
Full schedule can be found here, and match times added to the challonge website soon.
