I do think the question is worth asking though - the game is one month away, why haven't we seen any footage of a "traditional" dungeon yet, especially the typical early game "first dungeon" that they are always so proud to show off and excite people with? Why have they been showing nothing but shrines? I'm curious too. I don't think the answer being "BECAUSE SPOILERS!!!!" is really valid. That's now how marketing works, especially if this is a huge 50-100 hour open world game. If you have something impressive early in the game, you want everyone to see it.
This kinda reminds me of the MGSV situation with boss fights. I was certain that there would be pretty much no traditional MGS boss fights in the game. When I voiced this concern citing how they only showed Quiet over and over and had no mention or visuals hinting at any other bosses other than the Metal Gear, and pointing out how Peace Walker already followed this format, the diehard fans were telling me that I was being silly and that there's "no way" a numbered MGS would not have the traditional enemy squad bosses. Well, we all know how that turned out.
I trust Nintendo though. I will trust them until they break my heart. If they do I'll just open a bottle of vodka and play
this while crying myself to sleep.
