I don't think there's a Direct coming because Nintendo is a wild horse and one would think everyone in this thread would realize that by now.
Some people in the SMTV thread have pointed out that there hasn't been a new SMTV trailer or SMTV News segment yet. They said on the last SMTV News segment that September's would be late in the month, and the theory was that it would be after a new trailer is shown in a Direct. I still doubt this, because with all the previous monthly trailers, they announced it about 24h in advance, along with the SMTV News video a week later. They could still announce a new trailer tonight, it airs tomorrow, with the SMTV News on the 29th.
