That has definitely been rumored and would be consistent with what I think we’ve all come to expect from Google. It doesn’t seem to be announced yet though, and Waze recently expanded to support built-in infotainment systems.

Yet for the moment, Waze and Google Maps remain separate products with different capabilities. Waze still seems to be the best for real time information while driving a car, though it has declined some, and I’m surprised Google hasn’t killed it.
