Way to early to say.
Move to the bigger cars will limit some circuits like Monaco, but thats never really been a race just a showboat for F1.
The Yanks want to turn it into 'Superbowl' type events, marching bands and all that razzle, maybe not what the rest of the world wants to see.
Silverstone is now the only circuit in the UK deemed as safe for F1, so if it goes we lose it period.
Ross Brawn is involved and hopefully he will keep his feet on the ground.
Bernie will be missed though, ruled with a rod of iron, the wagons had to be parked inch perfect, or you heard from him, and that was how the rest of it was run, and it worked.
2017 will be a make or break year, bring it on......
