I have been worried about motogp fro a few years now as the grid got smaller and smaller.
They need to look at the costs and reduce them down slightly to get the grid full again. They also need to get the manufacturers back, suzuki are needed, BMW still makes no sense why they have not got involved and i can;t see Audi wanting to let Ducati compete likethis season again as they never do motorsport unless theres a benfit to the brand.
As far as who will be filling Stoners place, you can bet your bottom dollar that Doviy will be back in honda overalls next season.
I would guess we may see stoner out for a while then would not be surprised if he popped up in superbikes. 26 is too young to retire long term
