Since no Apple employees participate in these public, user-supported communities, there will be no Apple communication about future product planning. As fellow users, we cannot speculate about Apple's product planning for any of their products, regardless of observed release timeframes.
Pages, Numbers, and Keynote were and remain intentionally designed consumer and possibly prosumer applications. That is the intended market and only those that attempt to use them as though they were professional-grade tools assign that identity to them. Contrast this with MS Office whose primary usage group is still corporations that have provided 35 years of feature requests for a paid application suite. That is the principal difference between a Microsoft office solution and Apple's tools.
You have not expanded on your reasoning for MS Office (single-purchase, or subscription) avoidance. There are other Microsoft document compatible office suites, both free and paid that are available. The hidden cost is the learning curve.
I happen to maintain current versions of Pages, Numbers, and Keynote on macOS Tahoe 26.1. There is also LibreOffice 25.8.3, and MS Office 2024 for Mac installed. If I know that the document will travel to those that are using MS Office, I will generate the original in MS Office rather than risk an enigma export from Apple's applications.
