By the looks of the bag I'm guessing 1500 Target ID segments with the ability to notch (turn on or off) each segment individually. It also looks like a color screen with a new style control panel. The coil looks like the FBS II. Looks much lighter as well. Don't know if I like the change in the trigger PP over the button. Rumor has it as the first personal detector to go 20+" as well as a big increase in sensitivity to small gold
The only thing I can think of that would be more sensational than the CTX would be a pinpointer with discrimination just like the X-1 but wireless. Other than that, it's gonna have to be some kind of imager.
