The phones in question - Moto Z2 Force, Moto Z2 Play and Moto X4 - are now being sold for a much less than originally. From today until May 26th you can get Moto Z2 Force at $220 off, Moto Z2 Play at $150 off and Moto X4 at $100 off. While not new, these are still solid devices, so it may be a good idea to make note of Motorola's generous offer.
As for something new, Moto Z3 should be out sometime around Q3 2018.
