I can't tell from the article if MBs are being phased out and then will be no longer used, requiring phone/watch use (or KTTW) on Jan.1, 2021 or if you'll just have to buy them and still have the option of using them? It isn't much of an issue anymore for our family as both our boys have phones of their own and can use ApplePay to buy snacks, charge things back to the room, which was a huge benefit of the MB (and letting them get back into the room). Also, really enjoyed that MBs are waterproof and didn't have to take them off the whole trip. Now, my big concern is Disney getting themselves together with their app since that thing has pretty much been garbage as long as we've used it! If they are going to implement the phones to work like DLR, then we had no issue with photopass and ride pics (but then again, DLR doesn't implement MBs at all)!
