Here is some interesting news & new rumor. Apparently Motorola has filed some new patents for possible "disconnected" type of mods. The new rumors suggest that these new mods would connect to the phone for initial setup & pairing but then could be used in a disconnected status afterward, staying connected to the phone via WiFi or Bluetooth when needed. That could explain why we have not seen any new Moto Mods with, or since, the Z3 was announced last year. Perhaps they are moving in a new direction, and looking at ways to move the Moto Mod idea forward? I guess we will have to wait & see what happens this Summer. If there really is going to be a Z4 it would be nice to see the previous generations of Moto Mods continue to work while physically connected, and then these new mods with this new "disconnected" functionality.
