We know two "facts" (well Neo is still a rumour, but we all know it's true):
- Neo can't have exclusive games. Sony explicitely said all Neo games have to be playable on PS4.
At least for now, this will probably change 3 years or so later, when the next model ("PS5") releases.
- PSVR games have to run at least at stable 60FPS on the base PS4. If it's not, it won't get a "ok" from Sony.
So that shouldn't be the reason, since Neo can't have (PSVR)-games that are not running on the base PS4.
I think this comment should be understood as "was" like Nullpointer already pointed out.
