Any New Subway Cars After R262?

It's abundantly clear that the final of the pre-NTT NYC subway trains will be the R62/R62A, to be replaced by something along the lines of the R262. This would end what has been a pretty significantly long run of regular fleet replacements.

What then, though? The R142/R142A family would become your elder statesmen with plenty of years left. Would the fleet just sit in stasis running the system as-is for a decade plus?

I know we've seen some gaps between new rolling stock, but this would be a pretty lengthy pause.
