Define "traditional dungeon"
We're fairly sure that we're getting at least 4 distinct, themed puzzle locations. The Gerudo building rising out of the sand, the inside of Death Mountain, the cyclone over Hebra, and a collection of sky islands over the Zora's Domain. They'll probably be more similar structurally to the Divine Beasts (the shot of the Zora dungeon has a set of what seem to be 5 water locks visible, and the artbook has a shot of 5 lizard head things in front of a door) but with distinct theming and unique bosses instead of a joint Sheikah theming and Blights. We don't really know if dungeon items or an equivalent will make it back (well, there's indication of some items that may be found in dungeons, like the wingsuit from the trailer, and we might get powers from the central MacGuffins that are presumably found in these dungeons, but no indication dungeon design will reflect that)
