A lot of changes are coming to GSL tour in general in 2012.
First, as you may already know, main GSL Code S RO 32 - RO 16 will no longer end with BO 1 dual tournament, but instead, BO 3 dual tournament. Due to the increased number of games played, only one group will play per day. The result is that GSL season will last 8 weeks total.
Code S group nomination procedure also changed; In 2012, the group nomination will take place right before the start of RO 16. RO 32 will have 8 seeders placed in the groups, then rest of the players will be selected by RNG. After the end of RO 32, there will be group nomination procedure before RO 16 starts.
Tournament procedure RO 8 and above remains the same; RO 8 and semi-finals have BO 5, and finals BO 7. The up and downs match will remain the same, and Code A / code upgrade matches will remain the same.
With increase in the length of each season, 2012 will see total of 5 GSL seasons.
Second (and probably a very disappointing news for many of the readers), World Championship and Super Tournament will no longer take place in 2012.
Third, there's a small change to GSL prize money. Code S prize money has not changed. But Code A prize money has increased by roughly 2 times the previous amount. As a result of this, Code A prize money will now differ based on the player prowess. In this case, if players in Code S falls down to Code A, they will receive Code S prize money only, and will not receive additional money from Code A. For example, a Code S player who got eliminated at Code S RO 32, then managed to go far in Code A, he or she will only receive 1,500,000 won total.
Code A prize money will be as follows:
RO 48: 400,000 won
RO 32: 600,000 won
RO 24: 800,000 won
RO 12: 1,000,000 won
2012 GSL Season 1 -- the start of 2012 GSL tour -- will start in January 9th.
Fourth, GSTL has changed to double-elimination, 3 round system in 2012. The reason behind double elimination is to remedy the problem relating to best players from each team being unable to play due to the full league method. It also has been modified to allow more teams / foreign teams to participate, instead of the existing teams only.
Quick description of how this works: Assuming there are 10 teams active, the two seeded teams will go straight to the second round. Those that didn't get seeded will participate in the first round, and winning two teams will move to the second round. The losing teams will go through loser's bracket and the winner of that will move onto the second round. For the first 2012 GSTL season, the 2011 GSTL Season 1 winner MvP and the runner-up Prime will receive the seeds.
The second round will have two groups, and will proceed as a dual tournament. Four teams (the seeded team, two 1st round winners, and 1 winning team from loser's bracket) will duke it out, and the group's 1st and 2nd place winners will move onto the semi-finals.
The semi-finals will proceed as a cross tournament -- Group A 1st place will battle Group B 2nd place, and Group B 1st place will battle Group A 2nd place.
Two winning teams from that will move onto the finals.
GSTL will take place in Friday / Saturday every week, and first 2012 GSTL will start in January 27th.
Also, GSTL prize money has increased:
Winner: 30,000,000 won
Runner-up: 15,000,000 won
Semi-finalists: 4,000,000 won
RO 8: 2,000,000 won
RO 10: 1,000,000 won
