What happens when my timeshare I still owe on gets foreclosed?

I know it will badley affect my credit, but can they sue me for the difference between what I owe and what they can sell it for? Do timeshares get auction off? Can they garnish my wages, will I be able to keep my condo? What happens if I never pay the difference owed? I've read alot on the internet but haven't seen anything from someone who actually went through with the foreclosure.
