What would please me most (LotR)

My fondest desire, regarding the third LotR movie, is the following: At the very end, after all the credits and theme music, we see the words "the following preview is suitable for all audiences." Then a three minute preview of a movie filmed at the same time as LotR, secretly, nobody leaking anything about it. A complete surprise. "The Hobbit." That's my desire. I'm getting teary-eyed even thinking about the possibility. But alas, tis only my desire, and I doubt it will be done.

Oh, well, back to work I go...
