The above is dead accurate.Fall 2021 is a year further than expected making the current NX on a longish 7-year cycle.
Speculation on the 4-5 powertrain options?
2L N/A ICE Direct Shift CVT (i.e. UX, Corolla, etc)
2L T ICE 8-speed (or new 10-speed would be nice) (i.e. current engine carried over with minor refinements/bump in power)
2.5 L Hybrid CVT (i.e. RAV 4, Camry, ES, etc)
2.5 L PHEV CVT (i.e. RAV 4 PHEV)
