The advertised “regular device upgrades” will never happen for anyone as part of Pixel Pass, even customers who battled Google’s servers to order a Pixel 6 the moment they became available (it’s me; I’m one of those people) because there’s still more than a month to go before the very first customers in would cross the two-year mark and be eligible to upgrade.

So a core part of the premise of Pixel Pass (device upgrades) is being lost, even to existing Pixel Pass users.

Original marketing from 2021:

Pixel Pass brings together the latest Pixel phone with Google’s best mobile services, device protection and regular device upgrades — all in one easy subscription. (emphasis added)
