The issue with this kind of thinking though is that EVERYTHING works like that. Home many apps are in the iOS store right now that exclusively work on iPhone 8 or iOS11? None. So should that mean that Apple shouldn't roll out an iPhone 8 or iOS11 until more than the minority of "software" exclusively for new hardware is on those virtual shelves?
How many Mac apps exclusively for iMac Pro is in the Mac app store right now? None. So should Apple hold off on developing new Macs until that store is increasingly loaded with software explicitly for new hardware?
How many PS5 games are on shelves now? How many Xbox <next console> games are on shelves now? And on and on.
Video is just "software" for hardware players. If everything in the iTunes store today could roll out a 4K version of the software for 4K
TV's, how much money could be made for all the work in creating those versions? Not $1. Why not? Because hardware must lead. You roll out a 4K
TV or an iPhone 8 or an iMac Pro or a PS5 with new hardware capabilities and the software follows to exploit the new capabilities. It never works the other way because no one can make a buck on software that has nothing on which to run.
Was there an
TV4 app store full of apps well before there was an
TV4? No. Why not? Hardware must lead. Roll out hardware newly capable of something and software follows.
This will be no different. Retail shelves always lag behind "latest & greatest" hardware. If we have to wait until software climbs out of the minority before rolling out any new hardware on which such software is meant to run, almost all technical innovation ceases with the "as is" because the "as is" is where the software money can be made now.
Will consumers actively take up 4K? Will consumers actively take up a PS5 when that arrives? Will they take up an iPhone 8 when that arrives? The answer here is, does it even matter? If better hardware is rolled out and consumers don't take up 4K, that better hardware will still play 1080p or 720p or SD to it's fullest potential. It's hardware will likely run faster & better. It may come with a few other hardware features to make other parts of the
TV experience better. No big loss if consumers take this up or not.
Look for example at TouchID or Apple Pay. Neither of those had any Apple consumer uptake before they were implemented. But Apple rolled them out anyway. Software in general is still "catching up" to using either or both technologies but I wouldn't want the pace of uptake to make Apple hold back rolling such hardware advances out. Instead, I'd rather they roll the advances out so that the software and update can opt to take them up.
