Unfortionately the control tyre has also not worked, something bridgestone should be blamed for (and consistant as they also did a terrible job of producing a tyre for good racing in F1, why would they be signed again? I hope there are some significant performance aspects to the contract.)
Keep in mind that Bridgestone do NOT want to be a control tire supplier. As Bridgestone have said on many occasions, single supplier only generates negative press b/c the riders can only complain. Tires never make the difference between a win and a loss. If you remember back to 2007-2008, Bridgestone didn't even want to supply Rossi b/c they thought it was worth more to the company for advertising and development to beat Rossi/Michelin.
Bridgestone are probably just going through the motions, and Dorna's cost target for tires likely prohibits Bstone from making anything revolutionary. Dorna have hired Bstones ex-racing-director. I'm quite certain Bridgestone, Dorna, and the new consultant, whose name eludes me, are working on some kind of tire war regulations.
