I don't think that's going to happen. GV has been around since 2009 - I got my number then and it's been great. This is not Reader - several million people and businesses have GV numbers. Of course it can happen, and there may be other reasons you might not want Google to handle your phone calls, but I estimate the probability of Google just shutting this down as pretty small.

At worst you'll have to transfer your number to some other service. While I wouldn't be shocked by Google shutting down Voice, I would be shocked if it just abruptly vanished one day with no warning.
