I've advocated for Smash Ultimate DX with the resources of a true Smash 6 since even before official support ended for Ultimate after Sora's patch and the final balance update. I would have kept doing so whether or not my position was strengthened by this direct or not, but it has been, and while I no doubt am excited about the possibilities of this hypothetical release for the next phase of Smash on this system, I also understand it's in no way a guarantee things will be this way nor that Nintendo will live up to my expectations for such a release.
That being said I'd like to refocus on my idea of how this kind of release could work financially with the new information we have in mind. I want to be short and concise instead of over explaining why I think this or that makes sense.
Smash Ultimate sold around 35 million copies but is STILL only the 3rd best selling Switch 1 game demonstrating there is a larger Nintendo audience for this game still not yet convinced to play the most casual friendly fighting game on market. Building off Ultimate's success directly seems like a winning strategy in my eyes while also playing it somewhat safe.
So here's my plan I'd present to Nintendo how I'd do things and I wouldn't be surprised if I'm actually relatively close to their real internal plans for this game if it exists.
You can split Ultimate's audience into 2 groups. People that own Smash Ultimate already but no/some/all of the DLC fighters, and people that don't own Smash Ultimate at all. We have to factor in each group and find some kind of release synergy that works for them all individually while also collectively uniting them.
Smash Ultimate owners have to get an upgrade pack to the Switch 2 version at whatever price. This upgrade also includes plenty of quality life improvements to things like netcode, framerate, 4k/hdr support and other optimizations of the same likeness and maybe even some fun additional modes. It also nets purchasers Piranha Plant I guess as a bonus maybe if you didn't already have him.
People that don't already own Ultimate obviously just buy the Switch 2 version AND potentially both Fighter passes should they choose because we're leaving both Fighter Passes untouched as a means sidestepping negotiations. We find out that it turns out Nintendo probably DID have some sort of clause that allowed them to re-release Ultimate on future consoles.
As a quick little extra point of prediction I'd go as far to say that Switch 1 Ultimate online is shut down to incentivize people away from it but you can still play your Switch 1 version on its last patch locally to your heart's content.
Okay but this is now just a true boring port though right? Not the Smash Ultimate DX with the resources of a Smash 6 I was hyping up at all. This leads me to my boldest proposal.
Let's play Smash Ultimate Expansion Pack! Turns out Sakurai was working on Air Riders and this Expansion pack + Switch 2 update for Ultimate with Bamco this entire time and this expansion pack is as vast and content rich as any individual Smash 6 would have been only it's being added on top of Ultimate's already content rich base. This upgrade is ONLY compatible with the Switch 2 version of Ultimate. You can opt to instead purchase the Switch 2 version only if you want and still play with people that own the Expansion Pack but you cannot buy the Expansion Pack without owning the Switch 2 version of Ultimate. This Expansion Pack adds new mechanics, stages, characters, items, costumes, modes, options and all that good stuff you'd want from a bigger/better Smash Ultimate.
So basically if you own Ultimate you have to buy the Switch 2 upgrade and potentially whatever Switch 1 Ultimate DLC fighters you're missing and now this Expansion Pack whereas if you don't own Ultimate you have to buy the Switch 2 version, whatever DLC fighters you want from Switch 1 Ultimate you desire to have, and this Expansion Pack. That is if you want the full game. So taking everything into account there's a Switch 2 version of Ultimate you either have to upgrade to or purchase outright serving as the base, Fighters Pass 1 and 2 from Switch 1 Ultimate still their own separate purchases and this new Ultimate DX Expansion Pack.
Sidenote if a character from the fighters pass gets like a new move or something that's automatically incorporated into your game once you own Switch 2 version should you also own them.
Lastly Smash Ultimate Expansion Pack is a really boring name and I wanna stick to my guns here and give it the english name I think works best with the least amount of changes. Introducing Super Smash Bros Ultimate Ultra! Tells market and your entire potential audience exactly what this game is in the most exciting way possible. You can also go with Ultra Ultimate or Ultramate if you're feeling cheeky.
These are my thoughts on how a Smash Ultimate DX given the resources of a Smash 6 could actually work well. If you read thanks for your time and feel free to share your thoughts if you wish.
