Just being cautiously optimistic here.
Take a look at the Nintendo Direct mini from 1.11.2018. This was 14 minutes long.
A minute of The World Ends With You: Final Remix, a minute of Pokken Tournament DX DLC, a minute of Kirby Star Allies DLC, a very brief reminder of Dragon Quest Builders demo, a minute of Hyrule Warriors DE, a minute of Mario Tennis Aces, a minute of Ys VIII, a minute of Super Mario Odyssey DLC, a minute of SNK Heroines, a minute of Mario Rabbids DLC. There's more after that, but so far that's about 10 minutes of content. The "one more thing" for this direct was Dark Souls, which is relatively not that impressive since it's just a remaster of a really old game that's now multiplatform. But I don't recall people hating on it very much.
Granted that a lot of these were announcements of ports and DLCs of existing games, we could still be looking at least 9-10 different things. I should also note that a lot of these DLC were quite meaty and free to boot. Unlike a regular direct, a mini only gives about a minute per announcement. All of the games above aren't games worth giving more than a minute, but a lot of them were still substantial.
Will this be a mindblowing Direct? Definitely not. Will it have a thing or two that'll peak our interest? Definitely.
