Don't care for the gesturing with no buttons option. Don't care for the price. My P2 still operates like it's brand new. For me personally updating would be silly, not at all necessary, so why do it as I have no problem with using my P2 for at least another year. The new cam on the P3's does not entice me either, the P2 cam is awesome. Selfies are not my thing either so thats not enticing. All the complaints I hear around the web regarding the notch and the price increase makes me a tad concerned about sales and whether the pixel line will continue, Time will tell.
If there is a P4 I'd be interested to see what it's like. I may even pick up a brand new P2 at a later date on the cheap just to have a good backup device.
