I can agree that 3Ds was a mistake, but really, unless you've gone and learned everything and started looking as close as you can in this game, you can't really fully appreciate the changes. I'm obviously not going to be able to change your mind with this not being possible to be either a DLC or Updates. This took way more development time then would have been called "Port" or "Same Game". After Smash 4 was released, Sakuri left everything else for his development team to work on and started working straight away on Ultimate. With the massive character design Changes to characters such as Gannondorf, Wolf, Zelda, Mr. Game & Watch, Shiek, and more, there is no possible way that would work as an update for the Wii U. This simply is an entirely different game.
Plus the physics for the game work completely different and more like Melee then Smash 4. On top of that, with the complete changes and additions to previous mechanics that couldn't be seen as an Update, that's just complete overhauls. People need to honestly just look at this face value as a new game and stop debating if it's a minor update or a port. This changes far to much to be simply a port, and if this were "an update" that's like changing Fortnite to PubG. They seem similar enough but they have completely different gameplay and things to enjoy about them. Plus, we haven't even seen this games side content. We have no idea if Ultimate has anything like Subspace, Classic, Target Practice, and anything else that was not in Smash for Wii U.
I'm done debating. You seem pretty set in stone with not wanting to change how you see this.
