Why would they go up?
The M2 Air got a price increase because of the redesign. The M2 Pro 13” was the same price as the M1.
I am not convinced there will be a price hike for a M2 Pro/Max MBP with no redesign. Yes there is inflation, but the US dollar is also up, which effectively reduces manufacturing costs. I guess Apple could bump up prices just because people are expecting them bump up prices, so hey why not - more profit! But again, I am not convinced there will be any price hike.
Hm.. Maybe just it was just in Europe and Norway, the price of the basic Macbook Pro M2 went up.
There are a number of reasons why the prices could go up. UK expects prices to rise with 18%. (London British consumer price inflation is set to peak at 18% — nine times the Bank of England's target — in early 2023)
Anyway. I might buy a mac after Christmas anyway, price rise or not. Guessing that any Macbook Pro 16# Pro/Max M2 are mostly available after New Year anyway.
