Should I buy the pixel 9 pro?.

I need help I don't know what to do I have the pixel 8 pro but want the smaller pixel 9 pro but really do not know if it's worth it.. Should I wait another couple years to see if they're phones will be a decent upgrade or not? Is it worth upgrading from the pixel 8 pro to the pixel 9 pro? Thoughts anyone??? Would be much appreciated 😊

I do love my pixel 8 pro it has decent battery life and amazing cameras I'm glad I made the switch from iPhone but I don't know if I should keep this phone for another couple years to see what else they bring to they're phones before upgrading I suppose it's not so bad having a big phone for the time being lol.. Please no immature people being cheeky or leaving snide remarks thanks👍🏻
