Just checked and there are only 128 seats left, for this package, in the lower sections seats. That's about 2500 seats. Looks like it could be a couple of sellouts! The games are January 15 (CSU) and Feb 24 (Butler)
Although many of this ticket package have gone to fans wanting to see Butler only, still, there should be a pretty good crowd for the CSU game. Right now, there are only 22 seats available in the entire lower sections. Still lots of room up above, which will undoubtedly go once the Butler single game tickets go on sale.
