Before the official announcement, like 10 hours before, a thread was posted in which an Anonymous source sent info to Resetera Mod. They mentioned PC Gamepass tier going away in 2026, along with a free xCloud tier with Ads.
So after the announcement, PC Gamepass tier is de-emphasized for new signups. They also stopped mentioning it in the Coming Soon to Gamepass infographic that they post on their Xbox wire blog post every two weeks.
So what's likely to happen is that sometime middle of 2026, probably around May is when they get the bad news out of the way before June showcase, they will stop allowing any new signups to PC Gamepass tier.
They will do what they did with Gamepass Console $11 tier users before Standard was introduced. As long as they have Recurring Billing ON, they get to keep that tier, but soon as they stop, they can never rejoin. That way they won't piss off the recurring subscribed userbase.
Premium is meant to be the replacement once it has parity with the PC catalog minus Day 1 Games. And only Ultimate will have Day 1 Games plus EA, Ubisoft, and FortNite benefits. Premium gets the Day 1 games within 365 days.
So three universal tiers across the full Ecosystem. Then in November 2026, for the Xbox 25th anniversary, is likely when they may announce the online paywall going away for next gen Magnus hardware. They should also have the Xbox Mobile Store on Android up by June, if the judge approves Google/Epic settlement. And mobile would be added to the three main Gamepass tiers.
