Who knows.
At one point during the production of "Voyager", they toyed with the idea of having the USS Voyager and Janeway meeting whatever V'ger had become. But Stephen Collins was busy with "Seventh Heaven", Persis Khambatta had died, and it was realized that with all the wonders out there to explore, why would V'ger come back to our galaxy so soon, just to meet its namesake?
Gene Roddenberry once joked that maybe the machine planet who repaired V'ger, and set it on the path to achieving consciousness, might have been the Borg Homeworld, and William Shatner then used this idea in one of his Shatnerverse novels.
