There was recent talk of going to 20 races in a season. With new tracks coming in Finland and Kazakhstan, it will be interesting to see what happens. Apparently Rossi isn't a fan of the Thailand track though:

"I was in Thailand for Yamaha two years ago and the track is not interesting," he said. "It’s very boring, has not a lot of corners, just long straights. I think it’s not the best place to go." "And also where is the track is quite bad, it’s far from everything." "So I’m not very happy to go to Thailand, essentially, on that track. But if we have to go, we’ll go."
