Apple should have gone the Playstation way and release a new Mx every 6 years or so, it's not like people require so much processing power. The intersection of hardware power vs software consumption was about 10 years ago. Only VR gear is lagging. Though I can't complain about being able to buy renewed Intel Macs for under $200.
Analysts suggest that March 2025 is a likely target for the launch, aligning with Apple's historical pattern of releasing new MacBook models during that month.
