this is the most intellectually interesting group stage system I've seen
I think it will end up sorting teams out more accurately than the "everyone plays everyone" system, and certainly more effectively than GSL style groups, although there's all the room in the world for me to be wrong.

It's quite straightforward! A Swiss system is basically an accelerated round robin. It's accelerated because it eliminates series between teams that have different results as the tournament progresses (between a team that's 3-0 and a team that's 0-3 for example). The underlying assumption is that those series can be eliminated because the 3-0 team will usually win anyway.
There'll be 4 rounds of pairings. After the first round, you get 8 teams at 1-0 and 8 at 0-1. In round 2, the 8 1-0 teams play each other (leading to 4 2-0 teams and 4 1-1 teams) and the 0-1 teams play each other (leading to 4 0-2 teams and 4 1-1 teams). So you have 4 2-0 teams, 8 1-1 and 4 0-2 after round 2. In round 3 the 2-0 teams play each other (-> 2 3-0 teams and 2 2-1), the 1-1 teams play each other (-> 4 2-1 teams and 4 1-2) and the 0-2 teams play each other (-> 2 0-3 teams, 2 1-2). So you end up with 2 3-0 teams, 6 2-1 teams, 6 1-2 teams and 2 0-3 teams.
The 2 3-0 teams get seeded 1 and 2, the 0-3 teams 15 and 16 and the other 12 teams play one last round (2-1 teams get matched with each other and 1-2 teams get matched with each other). You get 3 3-1 teams seeded 3-5, 6 2-2 teams seeded 6-11 and 3 1-3 teams seeded 12-14.
Now obviously you lose some accuracy compared to a full round-robin, but in return you get a one-group group stage with Bo3. I'm not sure how much I like it for Dota since teams tend to be very close together and upsets abound, but then again, any other group stage system with this amount of games is also a bit of a crapshoot.

Never heard of the Swiss system before, but it seems like a good method for getting all the teams in the same group while keeping Bo3 sets. At first I was a bit worried about teams not knowing who their opponent is until right before they play, but it seems like this system is mostly used for competitions where multiple games are played in a row in one day in the same way dota is.

One tournament I played in that had that system was the national championship in chess. Since there was over 100 players in the youth group it was the most suitable system. Since everybody was there for over a week and thus wanted to play all days it created even match ups after 2 rounds and good games after 3. Liked the format ever since.
Man am I hyped for today, here's my predictions for the first round: Secret 2-0 VG.J iG 2-0 mouz Random 2-1 iG.V OG 2-1 SG TL 0-2 Thunderbirds Faceless 0-2 VP DC 1-2 Newbee EG 2-0 TnC

Nice predictions, although, i can't see Thunderbirds beating TL, gonna go with 2-1 TL. And probably DC 0-2 Newbee
