Dan, I reckon a few long term fans will leave, but most will probably keep watching and moan about the new rules on some car forum that Bernie doesn't care about. Getting the casuals onside is more important I'd imagine, because it expands the viewer base and it's a far bigger market.
Jetpilot, yes of course there are a handful of drivers that would do the job in the right car. I don't personally feel that Kimi is still in that group, even though he's one of my favourites. It really feels like he's in the twilight years of his career (relatively speaking), although I'd love to see him find his feet again and show them who's boss
