I mean I'm also disappointed by the slow pace of the transition, but they are clearly making progress towards it.

They've been _planning_ to move to PoS for ~3 years, with a much too optimistic timeline. In the meantime a lot of companies working towards that have collapsed or refocused on other efforts, delaying the whole transition. It will probably take another ~3 years (my personal estimate) until the transition is reasonably finished and core parts of the ecosystems have migrated, but at least it's moving into the right direction.
