This Winston Salem Journal link has a rumor of a Chip Ganassi and Petty Enterprises merger. They also go out and say that Gillett-Evernham-Motorsports is going over to Toyota next year.
I do not believe the GEM part of the link at all.
Scenedaily.com reports that Michael Waltrip racing is going to field cars for Michael Waltrip, David Reutimann, and Marcos Ambrose. No word yet on what happens to the #00 car. The link also says that J.J. Yeley will not be in the #00 car for Matinsville.
