DLR doesn't really announce refurbishments that far in advance, so it's hard to say what will or will not be closed. We do know that the Rivers of America (Tom Sawyers Island, Mark Twain, Columbia, and Canoes), the Train, and F! will all be dark for most/all of next year. There are rumors floating around that Soarin' and Jungle Cruise will be undergoing lengthy refurbishments at some point. Ultimately, it's possible that any ride could be closed for refurbishment at that point and we probably won't have a good idea of what will be down at that point until much closer to the date (e.g., February).
