The Sirius NASCAR channel will also see a combination of things like the NASCAR post race show using Claire B. Lang by mid-season was told and another XM racing talent moving over as well. Also hear the MLB and NFL deals will start seeing the two services combine talent, hope no one loses a gig with the merger.
