While this telescope is focused on high accuracy of closer stars, so it may not be finding any more galaxies, I wouldn't be surprised if it finds even more stars in the Milky Way than we previously estimated. This seems to happen every time we take a closer look.
From the article
it is likely also to see a colossal number of objects that have hitherto gone unrecorded - such as comets, asteroids, planets beyond our Solar System, cold dead stars, and even tepid stars that never quite fired into life.
It seems even the definition of star isn't always clear.
