For those that don't believe Sakurai's statement is compatible with the final Smash direct being in October, I quote this from Source Gamings translation -
"That said, if you were thinking that we’d just be dropping a bunch of newcomer trailers
all the way up until release, you’d be sorely mistaken. We may have gone a little bit overboard up until now, so we’re going to slow our pace from here on out."
This can be interpreted as we shouldn't expect trailers until release and instead we will get our final trailers this month. The slowing our pace part is, I admit, where it gets confusing. But between this, the final smash 4 Wii u direct being in October when the game released in December in Japan, Sakurai wanting to avoid leaks, and the release of the bundle on November 2nd, I predict we will have our final Smash direct by the end of October. Possibly as early as next week.
