Rumor has it that all of the new models will have that notch.

In fact, Android phones are now using the notch as well. I don't think it's going anywhere.

Unless Apple finds a magical way to hide the front camera and sensors under the screen with an undisclosed technology no one has heard about...you can bet the notch will stay in this year models and most probably next year too.
It's a non issue imho and Apple will never get rid of the camera and sensors...too many (useful) things rely on them...from FaceID to video calls etc etc...
Your biggest issue (only?) coming from a plus is the form factor imho and maybe some old games you can't live without.
Let us know when you check the models!!!
