That would only happen if all of v6's growth is coming from mobile users, no mobile networks are growing/deployed without v6, and also no users are dropping their wired connections.

You can look at the AS breakdowns on APNIC's stats and see that ASs that serve non-mobile customers are getting v6, and that some ASs for mobile users aren't. So no, it won't stall.

Slow down perhaps, but it has to slow down at some point or it'll go above 100%.
