Is it true about Mach 3

I hear Mach 3 is slowly phasing out and we will be forced to use Mach 4. Is there any truth to this?

I think mach 3 has been on life support for a few years now…the company has moved on to Mach4, but there’s such a big installed base of Mach3 users and so many hardware incompatibilities between controllers, that they continue to sell and support Mach3 and probably will for the foreseeable future.
