Will Windows (x64) Kept in Sync with Windows on Arm?

I’ve heard Paul talk many times about his frustration with the differences between versions of Office that have different features present for each version. (Classic Office, Office Cloud, etc.).

I’m wondering if, 1) The OS’s features will be kept in sync between the two versions (x64, ARM), and 2) Will the native versions of Office platforms be kept in sync. I’m referring to the classic version of Office.

If the two platforms are not in sync, that will make Paul’s job that much more difficult. Plus, I’m wondering because I’m planning on getting a Copilot+ PC, and I’m wondering if Microsoft is going to roll out features more slowly on the ARM versions since there will be so fewer people on it in the beginning.
