Looks like there were some solid matchups in the open bracket. Will replays be available?

yes, in roughtly 2 months when no1 cares.

In the past they have typically released the replay packs after the tournament. They changed a lot of stuff up this year though so there's no telling what they will do.

I assume in 2 years time in downtime at one of their tournaments they might show you replays of some of the games. So stay tuned in to MLGtv^tm.
