When the 2nm wafers start production. Think apple told TSMC to go to hell this year on their prices and a few others. 2026 or end of 2025 looks like when they'll hit, so I wouldn't be surprised with a 6090 for next year on 2nm process.
Then again they may wait for PCIe version 6 to become mainstream before releasing it which would make 5090 the best for many years to come. Panther lake is out, but only to select people, Intel finding overheating issues on PCIe version 6 atm, so we may not see new cpu's hit market till 2026, then 2027 as a mass adoption period when motherboards are out for it.
Can blame TSMC for holding world back this year, sad really. Karma going to bite them for their greed I suspect though, they could have lowered their wafer prices and made tons of money, now everyone will ditch them and get Intel, Samsung and some Japanese company to make them when their processes mature by end of year I suspect
