Time estimate for playerbase migration to 5.0.0

[Piezo_]

I was wondering if anyone could give me a rough estimate of how long it might take the majority (let's say 75%) of the playerbase to update their clients to 5.x, and how long they'll be waiting for things like
A. Their GNU/Linux distro's repositories to update the package
B. Their DRM-infested mobile fork to rebase itself on 5.0.0
etc.
