PS6 waiting until 2028? That's not unlikely. PS5 Pro already out Q4 2024 or before? Unlikely. I understand PS4 Pro launched 3 years after the OG PS4, but PS4 had far less shortages and the Pro was released because of the massive uptick in demand for 4K displays. 8K displays probably won't be relevant until the later 2020s or even the 2030s.
It also seems like overkill to support a higher spec PS5 already in 2024 when just now in 2023 AAA games are starting to die out on PS4 and Xbox One.
