funny coincidence how they seems to wait that Intel release their GPU before changing...
It's precisely that: a coincidence. And it's not funny that I can tell. The proof of stake transition for Ethereum has been pushed back many times already. Because Ethereum operates on a consensus voting for what to implement in terms of major changes, and the miners hold a LOT of sway, they keep saying the developers should delay the PoS switch. The only reason this coincides with the Intel Arc launch date is because they both happen to land in early 2022 now. Well, except Arc will come out first.
For reference, here are some of the times Ethereum 2.0 with PoS was supposed to go live:
January 2020? Ha. Hahahahahaaaa.
December 1, 2020? Didn't happen.
Multiple dates in 2021 all "slipped."
Now we're into mid-2022.
Realistically, if we get Ethereum full PoS by 2023 I'll be relatively surprised at this point. Also note that every major network update is a hard fork. All that needs to happen is for another "Ethereum Classic" to branch off and say it will never have Proof of Stake and will be mining forever, and there's a reasonable chance the miners will make that a more usable cryptocoin than the main Ethereum branch. Which is part of why the PoS switch keeps being delayed — no sense in going somewhere new that more than half of the users oppose.
