Whether they play out the 32 man bracket is completely dependent on whether they are doing full seeding or just using it for elimination. Given their history, I'd say it's MUCH more likely that they are doing the 'pool' bracket just for elims. In that case, just to avoid confusion to every involved, I made a test bracket.

the first round is neither winners nor losers. each subsequent round is winner/loser #, where # is the number of rounds into the tournament you are. i.e. after the first game, people are separated into Loser 1 and Winner 1
Start ------ 32 ENTRANTS
First round plays, nobody is eliminated, 16 are moved to loser 1, 16 proceed to Winner 1. ------ 32 PLAYERS
Loser 1 plays, and 8 people are gone, 8 go to Loser 2 ------ 24 PLAYERS
Winner 1 plays, nobody is eliminated, 8 people go to Loser 2, 8 advance to winner 2 ------ 24 PLAYERS
Loser 2 plays, 8 people are eliminated, 8 go to loser 3 ------ 16 PLAYERS
Winner 2 plays, 4 go to Loser 4, 4 go to winner 3 ------ 16 PLAYERS
Loser 3 plays, 4 people are eliminated, 4 go to loser 4 ------ 12 PLAYERS
Loser 4 plays, 4 people are eliminated, 4 go to loser 5 ------ 8 PLAYERS
and then you have a top 8, which I'm assuming Gigabits will stop with.
That means:
First round loss, and you have to win four matches
first round win, second round loss, and you have to win 3 more matches
First and second round wins, 3rd round loss, and you have to win 1 more match
first through third round wins, and you're in
so yeah, just a bit of info on how this system works.
