As Voyager is outside of the solar system, what is it's trajectory in the galaxy?

What is the future of voyager in millions and billions of years?  
Will it continue to orbit the galaxy if it doesn't hit anything in that period?  
How much will its orbit drift from the sun's? Is it possible that it could crash into a planet one day?

The most likely long-term fate of the Voyager is that it makes about 100 orbits around the galaxy, never hitting anything of consequence. That takes around 25 billion years. Some time after that ... maybe another 25 billion years ... it gets a gravity assist that flings it in some random direction. And almost all random directions are OUT of the galaxy. So then Voyager drifts out between the galaxies for 10^(20) times longer than its previous history. If it loses one (just 1!) atom per year to X-ray impacts, then in 10^(28) years it will have disintegrated to a cloud of gas (mostly iron).
