Will we be getting a higher voltage driver (96+V)

It is a market no one is touching under $50. Having an affordable driver able to do this would open up higher speed and torque projects. Most nema 17 motor coils should be able to take at least 140V before they damage themselves.

This may require a complete redesign as a lot of the drive circuit ICs are specced for lower voltages than that. Nevermind the trace separation needed.

@hYdos, I don't think it's worth the effort

I agree with @TamaBaka, usually drivers have up to 30V operating voltage and it's relatively easy to do.
For the 48V of the CLN17 V2.0 I had to try very hard to make the track gap about 0.375mm, although even that is not really enough to fully comply with the IPC2221A standards.
In the NEMA17 form factor I think 55V volts is close to the design limit, 100V seems impossible to me.
Plus it would be a lot more expensive, and there is little demand for such applications.

Maybe there will be such a possibility for CLN234, however there the limits will be 80V at best, and most likely the same 55V

So I don't plan to design for such high voltages (at least not in the foreseeable future)
