Doesn't complicate things at all. That's in the future. Which this wiki doesn't deal with. Once that episode has been officially released, then we'll tackle any resulting problems.
If we need to make changes, following the announcement will make our lives a lot easier should we need to make major changes. If some people edit according to what Moffat has said in one interview, and some edit according to what he said elsewhere, and some edit according to their interpretation of episodes, it'll be almost impossible to easily correct later on down the road.
