The core of the vintage remake market is "Always wanted this, still can only afford a clone" which is where Behringer lives.

There's also a "Always wanted this, can finally afford it now that I'm rich" niche for the high-end remakes from Korg and occasionally Moog etc.

There isn't a huge "Bought this forty years ago because I couldn't afford anything better and would quite like a modern remake" segment.

Casio do still make pianos and Casiotone keys which include samples and some CZ and VZ series sounds. (I don't know if they're sampled or DSP.)
