Rules for Capcom Cup Pro Tour Asian Finals:
http://www.beastapac.com/rules/
With Grand Finals being Best of 13, with a bracket reset, we might see 26 matches. Also, so far, Infiltration, Bonchan, Xian, Nemo, have qualified for the finals. With Taiwan, Hong Kong, Saigon, Cheng Du, and Singapore left.
If we see people like Xian keep on competing, as in people who already have CPT spots, but want to get into the CPTA finals and win, its a good chance that that this spot will go to an open spot. There's a good chance of this happening since Gamerbee is hosting and T.O.ing the Taiwan major, and guys like Tokido, and Momochi will likely go to either Hong Kong, Saigon, and Singapore. Infiltration already said he's going to Hong Kong, but he already has a spot, so if he wins again, it'll go to the 2nd place person.
Xhao Hai or Dark Jiewa will probably win the Cheng Du event.
