3 places I can think of are Glendale, Denver and Seattle I would also think San Diego, San Fran (Candlestick), and Vegas (albeit a tad small for a venue) could also have outside considerations. Vegas has NO chance because the Pac-12 doesn't have a school in Nevada. And if were going to be held in San Francisco, it would be at AT&T Park. The same place where the Kraft Bowl (formerly the Emerald Bowl) is hosted.
