Well, we didn't get that rumored "Goodbye Reggie" Direct, but we are getting something before E3.
Nintendo has just announced this morning that the next Direct on the table is all Super Mario Maker 2 related, and will be dropping post-haste. It's arriving tomorrow May 15 at 6PM ET as yet another evening (US) direct (I really miss the days when these were in the morning, marinating all day and not in the dead of night in Europe).
Nintendo says it's roughly 15 minutes and will solely cover Super Mario Maker 2, so don't get too excited. My guess is we'll get a look at each theme, as well as some more silly elements like amiibo support.
