If the data is still there to be saved they'll save it. I sent in my Wii a while back and they sent me a new one with my old save data already on it. But since a problem seems to be with the corrupt data, there's a possibility they can't salvage it.
I know I got the warranty extended an additional year after they fixed it, so I'd assume if it breaks down again within a year there should be no cost. But I'm not sure about this at all.
