You can add this to the growing list of evidence that suggests Utah is Pac-Ten bound. The Deseret News is reporting today the USC trustees were told by the Pacific Ten of their intentions to invite Utah for the 2011 (it seems) season. 

A Southern California source said at USC's trustees meeting Tuesday, they were told that the Pac-10 had authorized the negotiation of an offer to Utah. Everything is solid from the conference's standpoint and was subject only to Utah's agreement on terms.

So, as mentioned in the article, Utah to the conference seems like a formality now and I highly doubt the University is going to vote against leaving the Mountain West (if they haven't voted already).
