Evangelion and Shinkalion announced another cross promotional event
The Shinkalion movie is out on December 27th, maybe they'll show a new Shin Eva teaser alongside it.
They announced the crossover Not with Eva in general, but with Shin Eva. They'll show something for sure (after all there are 6 months before the movie is out, generally trailers come out during this period of time).
