After the PAC invite, Chris Hill and Utah completely changed up the schedule in order to play BYU in 2011 and 2012 -- buying out games vs. Iowa State and BSU. It wasn't cheap to get out of those games but Utah did it in the name of the rivalry. It shows Chris Hill and co. are dedicated to keeping the game going.
It's going to be tough to keep the Holy War on the schedule every year given the 9-game PAC schedule on the Big 10 scheduling agreement -- but it looks like it will be scheduled as often as possible.

It's way too big of a rivalry to let it disappear completely. It would be sweet to at least play it every other year. It will be especially cool to see a Holy War played out in a bowl game!
