To be absolutely honest, given something he revealed about the ending to "The Wings of Goodbye", not to mention what he managed to do with regards to the triangle in Frontier with that film (hint: you need to watch both the series AND the movies to fully appreciate it), I'd argue that Kawamori was just teasing us so that he could keep the end of the triangle under wraps.
At any rate, I'm just finding this all hilarious. ^^
