Nintendo has just announced a Partner Direct set to take place on July 31st at 6 AM P.T and 9AM ET. This comes just in the nick of time as a rumor by a known Nintendo leaker did state we would get a Nintendo Direct this month, and it comes at the very end of it.
This is partner direct so it will mostly revolve around third-party games, so I wouldn’t get my hopes up on hearing about their first-party titles.
The Direct will be around 25 minutes long so you can watch it relatively easily.
