Nintendo just put up a job listing, and as part of the description, the following was included:
Considering they included Nintendo Direct as part of that, it seems Directs will be continuing! I'm glad they don't currently have plans to discontinue it, it must just be on hiatus due to Iwata's passing.
Edits video/audio for TV commercials, game trailers, Nintendo Direct, web content, demo kiosks, internal and external presentations, and general marketing purposes as needed
