This new "R" trademark filed back in June could be for the rotary engine range extender that Mazda had planned to put in the 2022 MX-30. But earlier this month it was reported that a Mazda spokesperson said "the timing of its introduction is undecided."

Could this trademark be an early sign that Mazda is still trying to launch it in 2022? Or even in 2023? I know it isn't much to go off of but there's a good chance the rotary extender will still happen.
