This is true. The problem is PSVR is more consistent. Kinect had a huge surge that fell off rapidly. They had a few really good selling titles but the library of games fell out very fast with almost across the board bad reception. Not only that, developers hated it.
PSVR is steadily growing, but more importantly, the attach rate is very high since day one, not just a few titles either. I've often seen games like Borderlands 2 on PSVR on the best sellers list on Amazon. Wtf? Borderlands 2 in 2018? Yes. It was outselling brand new normal PS4 games with a 90 million install base compared to the 4 million PSVR install base. They eat it up like candy. Astro Bot, Skyrim, Beat Saber, and Doom were other games I noticed topping the Amazon charts. That's really insane when you think about it.
On a chart, Kinect spiked upward and flatlined, PSVR(and VR in general) is a constant upward slope in sales, not crazy drastic, but Sony understands they don't need many PSVR owners to be profitable, they buy the f*** outta games. I'm one of them, I have 3x more PSVR than regular PS4, despite less time owning PSVR. It's really a different culture of passionate gamers. All Sony needs is to get more people to try it. Most gamers still think VR is just a "screen close to your face." That will change. PSVR is coming to a local mall near you.
