I wonder if the old machines will be in use for off-site guests, or if all will get wristbands?
I'm not sure if on-site guests will have perks (perhaps extra FPs?), though it wouldn't surprise me. Rumor has it that they are trimming down free dining (nothing for value stays, quick service for mods and deluxes) and offering FP perks is a way to entice guests to stay onsite when the resort prices keep climbing and promotions such as FD are not as good as they once were.
I also wonder how this would work for those w/o smart phones and for international guests in the parks if they want to change a reservation or FP time.
I don't mind wearing a bracelet, but I do hope it's removable for showering and sleeping.
It'll be interesting to see what develops! We won't be at WDW until Sept., so hopefully by then the system will be up and running well.
