Changes at Indianapolis Motor Speedway?

I saw an article today with the following:

"Out at the Indianapolis Motor Speedway this afternoon, track officials are expected to announce the addition of NASCAR Nationwide and Grand-Am Rolex Series races to the Brickyard 400 weekend in 2012."

The Nationwide race doesn't do much for me but I'm really excited to get the chance to see the Grand-Am Rolex guys locally. My only concern is that these two series (NASCAR and G/A Rolex) are about as far apart as you can get as far as the type of racing and general fan base. My stock car interest has been fading and I've been following more and more of the sports car races.

Anybody else have thoughts about sports at Indy?
