I want one, especially after getting into PlayStation with my PS4 Pro. Unfortunately, the memory cards are crazy expensive. And the PS TV model (less game compatibility) is getting really expensive.
If I ever get a Vita, it will not be for a while. I honestly doubt Sony will ever make another portable. If they do, I see it being a hybrid like the Switch.

Lifetime Sales Predictions 

PS4: 130 mil (was 100 million) Xbox One: 55 mil (was 50 mil) Switch: 110 million (was 73, then 96 million)

3DS: 75.5 mil (was 73, then 77 million)
