Rumour has it that NVIDIA is planning to release two new GeForce RTX generations in 2022, leaving the GeForce RTX 30 series as the only option for a while yet. Reputedly, NVIDIA's RTX 30 SUPER 'Ampere Refresh' will debut first, and will have around nine months on the shelves before RTX 40 'Lovelace' cards arrive. RDNA 3 and RTX 40 cards could arrive at nearly the same time, too.
