They wouldn’t obviously. Especially since VR content is significantly more expensive to develop. But that is an Apple problem to solve. If you want people to buy your $3,500 toy, you have to give them a reason to buy it. Personally if I was going to attract developers I would give them a real sweetheart deal, like for the first two years of the platform the developers keep 95% of the revenue. Yeah that means for 2 years I make no money on software but it also means at the end of two years there will be software to make money on. And make the whole thing bring dead easy to develop on. Have a whole bunch of tools to import existing 3D content or write games or whatever.
