I think there needs to be room for at least one race in Pocono...the race was really fun when they were allowed to shift, and if they brought shifting back, it would make for a fun and challenging event.
As for these 3 new entrants, I like Juan Pablo a little more after watching NASCAR in Primetime. Jacques Villeneuve will be interesting, but I'm not sure he can do much with Bill Davis Racing. Dario Franchitti will have success as he's done more ovals than JPM and JV, and also, I think that Ganassi will be on the rise with their new approach. Scott Speed won't do well. He wasn't committed to F1, but got away a little because he raced similar cars before. However, to learn a totally different car, he'll need to be patient and diligent, which I don't think he can be. Regardless, the road courses will be fun. It'd be really cool if they had rain for one!
