Is Voyager's velocity great enough to eventually leave the solar system? 

I'm not sure I'm asking this properly. I'm asking, essentially, if Voyager will legitimately leave the solar system entirely, eventually passing through the outer limits of the Oort Cloud and moving on. Or is it more likely that eventually the drag of the Sun's gravity will cause it to slow down and be captured in a very long orbit like a long-period comet? 

I ask because there's a common conception that Voyager's just going to go on in the direction it's moving forever. Maybe my question has to do with the escape velocity for the Solar System?

Voyager 1 and 2 both have velocities greater than that of our solar system's escape velocity.  They are currently leaving (or at least exploring the definition of the edge of) the solar system and - if not interfered with by the unlikely collision of another body with extremely unlikely perfect momentum to cause them to come back  - will never return.
