JMO here..
I would hope that it's not another ho-hum pick like J.R or Melanie, or the rest of the retreads posted..
No disrespect, they are nice drivers, but who really cares out there in TV land about the same old tired storyline re-run except the few who know them personally, or the few who are fans of them?
Over they years, there were hundreds of drivers who "shoulda" had the seat, but were moved out by more interesting prospects, so I never am a fan of a certain person just because they've been around the block. There's a TON of unprospected, championship caliber winning talent in the Sportsmen classes that would be Scelzi/Fuller-like perfect for the job.
I think it should be a fresh story, a fresh face, a new exciting prospect that interests people. Hopefully an exciting racer who is unbelievably excited, and has paid the dues and deserves a shot. And please, not another Force style nepotism driver who have to be trained on how to buckle up properly and how to adjust their hair color and lipstick shade for the right cloud cover. I think people see right through that stuff quite easily, and it makes it so easy to turn the channel..
