This is just pricing the same model to higher limits at a volume discount (which makes the pricing per usage lower, not higher). To actually "release a $200 model" they'd have to make something expensive to run like a ChatGPT 4.5 and then have the only plan which can use it worth a damn be that price. Given how bad 4.5 flopped in terms of performance I doubt many will go that route though, it'd have to be different kinds of services not in the current plan instead.
o1-pro (and high limit Deep Research) is technically the $200/mon offering. 4.5 is kind of a dud IMO, even in creative uses. That said gemini-2.5-pro is nearly as good if not better than o1-pro and now that Gemini has a Deep Research equivalent I'm finding it hard to justify the $200/mon sub.
