One thing that I've seen lately is that higher RAM and storage prices are affecting Macs now in the form of pushing out delivery dates; not higher prices. It also seems to be affecting the used Mac marketplace with far fewer Macs for sale and prices not really dropping. I was planning on upgrading my M1 Max Studio to an M5 Max Studio and the expected launch is WWDC but we'll see whether or not they are delayed.
For reference: if you want to order an M4 Max Studio, the arrival is estimated for the end of April. If you want to order a Studio with 256 GB of RAM, the arrival is early September. I do not need to upgrade so I can just wait. But I really don't like where the market is going with more shortages, delays, and maybe higher prices to come.
