At a Gravity Falls panel, Hirsch confirmed that Dipper 3 and 4 were still running around somewhere. He also confirmed that the twins still have most of the things they've collected from past episodes (such as the size changing crystal, the grappling hook, the president's key, etc.) It was insinuated that all of these things are likely to be seen again.
