Another point. Look at the sizing guide again. It says "Includes two bands". I think most people will interpret that as two complete and separate bands, not 'one fastener and two differently sized other halves'. If the latter is what Apple actually means then there will be lots of annoyed customers on April 24.
Annoyed customers because they can't swap out with someone else for a different color? I don't think Apple cares jack squat on a flying rock.
