The renovations did occur.. 2 years ago in fact.. the upper decks were added on each endzone, media and vip additions and various other addends to increase capacity from 76 to 92,000 which was shattered this season with 96k attending.
I will be getting a close up look of it in a couple of weeks in fact.
As far as the signed contract, every news story I find has the extension thru 2015 with the schools signing it in 2007.
and besides the RRR, there is the State Fair classic, and a new bowl in 2010 the dallas football classic between the big 10 and cusa.
