To my knowledge, Apple has never updated the design of the MBP in one year, and in the following year re-updated it. Think about the start up costs, to get the manufactoring process ready for the new design. The tooling alone is expensive, and then just throw that away and redo it all the following year? No, Apple will stick with the same design for a few years. They tend to stick with a design 4 to 5 years.
M2 Pro for sure, Oled - who knows. I'd vote no, but it is a possibility.
It appears price increases were mostly felt in the non-US regions but again its anyone's guess.
Without apple confirming what they will do, this is all speculation - we can take some level of common sense and prior history to say what they probably won't do, but its anyone's guess at what they will do
