"He admitted there will come a day when "we will have to electrify it, but we want to keep this pure concept." Joachim Kunz pointed out the MX-5 will not switch to an existing platform used by the other cars and SUVs since that would mean the loss of RWD. He went on to say most of the development work is done at home in Japan as the sporty roadster "is the baby of the headquarters."
While an exact date as to when the ND generation will be replaced was not provided, Kunz suggested it won't happen in the near future: "Having one generation for 10 years is not a problem for us."

His statement indicates the NE model is highly unlikely to come out before 2024 considering the current car was launched in 2014."
