When I see how fast Codex max thinking GPT 5.5 eats our enterprise seat credits almost anything else seems cheap (until we switch our live systems from 5.4 api to 5.5 api I guess)... good thing I'm not the one paying for those credits and tokens (which is probably how most of the money is going to be made on AI going forward, borderline free chatbots for normies are done)
5.3-Codex is really good enough, Sonnet 4.6 is good enough.
On my personal account, Copilot Pro+ still only gave me back Opus 4.7, whereas my work's Pro account still lets me use Opus 4.6.
So, my gut says, it's entirely possible that Pro+ will continue to have more segregation on model availability...

> Last week, we also rolled out temporary changes to Copilot Individual plans, including Free, Pro, Pro+, and Student, and paused self-serve Copilot Business plan purchases. These were reliability and performance measures as we prepare for the broader transition to usage-based billing. We will loosen usage limits once usage-based billing is in effect.
There's enough weasel wording here that I would expect only certain models get re-enabled on Pro.
e.x. lots of people seem to get good enough results from Opus 4.6, personally I prefer it over 4.7 in GH Copilot... locking that down to Pro+ would be, given this salvo of enshittification, a 'logical' move on their part.
