They did increase the base Ram for mac configurations in late 2024 from 8GB to 16GB.
While it wasn't a strict price decrease it was an improvement to the base model. The 24GB m3 air I bought a few months earlier would've been cheaper due to that if I held off for a few more months. Now w/ the price hikes the price I paid is now cheaper than buying a 24GB m5 air.
While these new Mac prices are probably here to stay, the upside is that once the AI market saturates and RAM prices fall, future Macs will likely get a significant memory boost at all price tiers.
A base-config 2028 MBP could be running local LLMs at a level unthinkable today.
