From what I've been able to gather, nothing has really changed since the season started other than maybe a few more GA tickets available for those who walk up to the ticket office, day of.
According to my most recent conversation with the ticket office, they supposedly requested the ability to increase capacity but were denied permission by TCU. She was unable to specify who exactly she meant by "TCU." I imagine it's some combination of the board & the chancellor (pressured by loud liberal faculty members) along with possible outside consultants.
Either way, shame on TCU for continuing to be a bunch of passive, spineless pansies.
