Hey Matt you're lucky. I also applied for the CDL ticket by the TeamAyu and I had 2 tickets, so I should say we are lucky. I also think that there are a lot of tickets reserved for the TeamAyu, I saw that in some japanese BBS, some people will be on the 2nd floor. So I should say I'm very lucky since I will be in the arena part.
I think to best way to have some tickets after the TA website is to pre-order them by the net.
I have 2 links the first seems to have some tickets for the CDL. Since I can't read japanese I not sure if you can apply or not but you can try them :
