I have a theory on why Disney may go with this approach over the traditional band. The obvious reason to me is that they'll be able to sell so many different bands to guest it won't be funny. You get your "puck" and a starter band (some generic color) but then they'll offer the special theme, characters, etc magic bands that all you have to do is pop the puck out and stick it in a new band. You can rock Mickey one day and Stitch the other, all without messing with
MDE.
And my conspiracy theory on why they are doing it is (puts on flame suit on) is because it will help limit people from creating phantom MDE accounts to get more FPs. They probably won't sell new transmitters in the stores.....only the bands, lanyards, keychains or whatever they come up with to hold the "puck". If you happen to misplace your transmitter you'll have to get it somewhere else. No unlinked bands means no phantom MDE accounts. It won't stop the practice completely but it will make it harder to do.
