Not in the slightest.
Waited a long time for this coming from 11 pro max. My old phone was quite abused I gotta say. The speakers were wearing out and kind of soft. The screen wasn’t as bright. And it was VERY laggy
I am very glad I upgraded this year. But also really glad I waited 4 years to truly feel like it is a substantial upgrade. Although I think they did a lot this time around incrementally from 14-15 PM (usb c, action button, newer and faster chip, more RAM), you are going to get all this and more next year.
For me the upgrade included all that and the dynamic island, always on display, promotion 120hz etc etc. it feels NEW. Plus I went to 1TB cuz why not.
If you wait a year, you might be as excited as I am. If you are happy with the 12 you have, keep it. This phone (and the associated features) aren’t going anywhere! It’ll be even better next time
