Betteridge's Law of Headlines still applies. Asking that question shows a misunderstanding of what a bubble is and also assumes that's what's happening right now is the only thing that will continue to happen into the future, rather than the ebbs and flows that come in any economic conditions.

The market will only bear X amount of some thing, and spending is slowing, so X has to lower with it. That affects all video games right now, from Fortnite to Shadow Gambit.
