I really don't want to wait. I want the bigger screen now. I love my Air 2, but I really don't like the screen size (too small). Obviously different strokes for different folks, but I'd hate to have a Mini. Portability would be nice, but I'd loathe the tiny screen.
I didn't have the cash on hand when iPP was released. Now I do. I've been waiting for a good sale. I prefer to buy it at BB to get the RZ points (the big purchase helps to make Elite/Elite Plus status for next year). I wasn't paying close enough attention to these boards or SD (spend too much $$ there when I'm on the site a lot), and I missed the Staples deal that started on the 14th. I would've matched it at BB and had one in hand now. The only thing better would be BB having it at that price and being able to use a 10% off mover's coupon with it.
That said, I was disappointed that the iPP didn't get a better camera than the Air 2, which was released a year earlier. I know lots of people don't care about tablet cameras. Some see no need for them at all. And while I agree you look like a dork taking pictures at a graduation with a tablet, I still want mine to have a nice camera. If I'm on my tablet at home and a child or a pet does something cute, I want to be able to take a pic or a video without putting down my tablet, picking up my phone, opening up the camera app, etc...
I was further disappointed to learn that the Air 3 (or Pro 9.7 or whatever it's being called) sounds like it's going to have everything the iPP has, only on a smaller screen. On top of that, some aspects of it may be better than the iPP (improved camera w/flash). Obviously it's a newer device, so upgrades can happen. But I want a reason other than the bigger screen to spend more for the iPP. I'm happy for those in the market for an Air 3 (happy it's getting everything they want it to have, save for maybe Force Touch). I'm disappointed personally though, as I want iPP to have things the others don't have (other than the bigger screen). I like exclusivity in my high $$ purchases.
Still not sure if I'm going to wait until next fall/spring/whenever the next iPP is released or not. I really want a bigger screen! I guess it depends on whether or not any more nice deals come soon. The longer it takes for another good deal to pop up, the greater the chance I'll wait it out.
