Since Valve’s Proton is built from Wine, to preempt the question — no, we don’t know exactly when Proton 10 will release after rebasing onto Wine 10. Proton 8 was released in April 2023, Proton 9 got a Beta in late April 2024 with a release in May, so it’s probably not likely until sometime around April / May.
