KU, KSU and ISU all in the same session means tickets are going to be expensive for Thursday Afternoon. probably have trouble selling tickets to the Thursday night session.
Tickets for Thursday night are already being dumped for $35. Ten $ below face value.
If OSU wins against Tech (very likely), the Thursday second session will be quite expensive. Best bet is to find $10 dollar ticket Wednesday night, make the commitment to get inside the Sprint center, and purchase tickets from losers before they hit the streets.
