This is complete speculation (my comment, not the great article), but I wonder if Apple will eventually go the CurrentC route and introduce a non-NFC payment component for all the non iPhone 6/6+'s / potentially Androiders out yonder. If so, they might have held out on announcing the functionality to get a boost in iPhone 6 sales. Certainly led to me feeling like I "had to" buy it "for work." Insert my girlfriend's incredulous face.
