It will be very much in keeping with Apple if they release a flat mobile OS, just like Windows and Android and everyone else these days, but then claim they have invented a new level of flatness that is superior to everyone else's flatness.
Apple will then patent flatness and sue everyone else for flat UI.
Honestly if Apple wants to be revolutionary bring back glass buttons and at least look different than all their competition.
Geeze, if this is Apple's idea of innovation, to duplicate other people's design trends now, its game over.
Dude,
While I hear you and what you are saying, let me remind you that we all have no idea what is coming. All these assumptions that is it going to be "just like Metro" (which sucks) boggles my mind. I bet things will be fine.
