Summarizing everything that has been said here, and all the speculation about Yamaha's future, aren't there really only four possible scenarios for what is happening? Are there any other scenarios that are not just variations on one of these four?
1. Yamaha is getting out of the snowmobile business, and letting its dealers and customers down slowly by reducing its line and limiting production of its sleds by AC;
2. Yamaha is getting back into the snowmobile business, and 2020 will see the introduction of Yamaha designed and built sleds;
3. Yamaha and AC will go their separate ways, but AC will develop a new chassis to replace the Pro Cross, and give Yamaha the rights to the old Pro Cross chassis in return for Yamaha continuing to supply 4-stroke engines to AC. Yamaha will build and improve on that foundation for the future; or
4. Yamaha and AC will deepen the existing partnership and jointly develop new sleds, and maybe Yamaha will even develop new 2-stroke engines to be shared with AC.
If we had the list of possible, or likely, scenarios, we could take a poll, and the winners of the poll would have serious bragging rights come March!
