There is evidence to suggest that AMD is readying the release of another Zen 4 processor model, though it may not be like any other Ryzen 7000 series SKUs that has come before it.
If gameplay on a budget is your main PC use, AMD's Ryzen 5 7600 is a reasonable and affordable CPU choice. With minimal cooling required, it will handle mainstream computing and gaming needs.
AMD's Ryzen 9 7900 has some of the best power efficiency and performance per watt among desktop CPUs. With its included cooler, it's a capable and low-power 12-core option, all for a similar price to the higher-end 7900X.
