This current generation doesn't give two fucks about the timing differential between older MPC sequencers and the new shit.

My guess is that a lot of the tablet sect only knows about it when they read about it online. Plus, these companies are generally looking for a quick buck and are more interested in packing features and high numbers of fx and presets than nailing down sequencer timing. It's just not a big enough issue to enough people for these companies to pay that much attention to detail in most cases.

Sure it's possible, but highly improbable.
