Extra challenges, new story and one new dungeon would sound like a very small deal if we were talking about Wind Waker or Twilight Princess, but we're talking about BotW...
Botw, a game where a dungeon could be days long to complete, the story could be bloody anything and it may not even take place in the massive overworld we'll come to know but perhaps a new island much like how Skyrim did it.
Witcher 3's expansions were larger than some games just on their own and with BotW being such a huge game the same could probably be true of its DLC as it is with the Witcher 3...
So, how long do you want the DLC story to be and how long are you expecting it to be?
