If I was targeting the PSVR hardware platform, ... I'd be very interested in knowing {long list}.

I can assure you -- as someone who has Occulus, Vive, and several other AR/VR solutions in the office for development purposes -- that you are not alone in your curiosity.

There are many major obstacles to overcome and many major tool sets that need to evolve first. Many companies are still struggling with what should be basics of the platforms, trying to display content correctly on a range of devices, particularly AR devices.

As one example of hundreds, developers can't just overlay things and call it good on AR systems, several AR displays require subtracting out 'real life' light; if you want to display a pixel of #FF433F you've got to figure out the real world has roughly #E8A56B at that location, then figure out based on lighting how much display light to add to generate your scene. Because light doesn't behave linearly and because you can't subtract light in the systems, you can't just try simple subtraction of #FF433f - #E8A56B. You need far more complex solutions to brighten and recolor based on environment.

As the technology stands right now it is a race to see who will generate the first killer app, the thing that everyone must have. Several companies have already made ventures, with Google Glass being the most mainstream, but generally none have gained big acceptance.

Personally I think you've got a few more rounds of innovation before it gains acceptance and succeeds. Although many people complained about it because complaining is trendy, I envision the killer platform to be something along the lines of Google Glass; a tiny always-worn device rather than the large bulky headsets out there today. It is going to need multiple cameras and world sensors but somehow be released in a way that doesn't offend the paranoid. The killer app will end up being something akin to Pokemon Go, something that is location dependent, requires people to get public exposure, encourages socially positive behavior, and cannot carry much social stigma. (Also, though most people hate to discuss it, the other killer app is going to be porn.)

There will be several more rounds of people introducing products, there will be products tied to PCs, products tethered to smart phones, products tethered to small computer packs, and these will all fail because the public won't accept them.

Then suddenly one day someone will introduce yet another augmented reality product and instead of failing like the last few hundred have done, the product will succeed spectacularly making the companies that launched it very rich. Many companies will invest a lot of money on the gamble that they will be the lucky one. And if they aren't the first one with the astronomical bank account, they will hope to be the second or third that only gets a colossal bank account, or maybe at least an also-ran that can recover the investment.

As consumers and game developers we benefit from that investment, so of course we are anxious for that day to come. We are quite close, but I don't see that day for at least another five years or so. When Sony's product finally hits the market this will probably still be a niche market. While the press releases on PSVR are quite impressive and AR/VR headsets are great pieces of technology, in many ways today's VR consoles are little better than the Virtual Boy that Nintendo failed with twenty years ago. They can do automatic positional tracking and more fancy colors, but the underlying problem of isolating the users remains.
