Personally I don’t think they’ll be joining the AAC. TDS will be their usual selves and demand more than they should. By losing Ucon, the AAC now has to split the money pie 11 ways instead of 12, and Ucon wasn’t making them money anyway, so they’ll all collect bigger paychecks without Ucon and the TDS.
Edit: I have no information to back that up. Just how I see things.
