Of course, that is very likely how it's going to play out. We know they'll go there. And then where will all the ("4K is gimmick", "4K is silly", "waste of bandwidth", "seating distance", "data caps", etc) people be when Apple rolls it out? We've been through this already. At one point, much of these same arguments against 4K were slung around here against 1080p... when Apple still clung to 720p. Then, Apple rolled out a 1080p

TV and it was crickets from the "gimmick", "bandwidth", "seating distance" gallery.
Apple will be quite happy to sell a 1080p

TV now and a 4K "upgrade" later. Lots of profit in that approach. At least around here, Apple can count on a good-sized vocal crowd who will work for free to market why we don't need what Apple isn't selling now and then flip to why we do need to upgrade to what Apple will be selling then. It's only "silly", "gimmick", "seating distances" today. Once Apple adopts it, it will be "shut up and take my money".
The migration from "720p is good enough" to 1080p was exactly the same.
