Yeah, no, very much disagree.  ESPECIALLY with Smash.  Smash 4 was held back by the 3DS so the Switch being more powerful and not having to deal with that will allow for a significant technical leap if Nintendo applies themselves to that.  Also, there's plenty of flaws in Smash as a package that need addressing.  Singleplayer is still very lacking is the most obvious one, online features could use enriching (there's much more that could be done to allow for you to create very specifically designed tournaments).  And there are plenty of new characters they could add. 

And this idea they've perfected a franchise has been put forth many times in the past with other franchises they have and thank goodness they didn't listen because otherwise there are great games we would have never gotten. 

And when I say they NEED it, I mean that right now they need all hands on deck, every big gun NEEDS to be here.  The Switch is coming off the heels of the Wii U, they need to make the absolute strongest impression possible and dropping two hugely hyped franchises would not help.  The Deluxe versions will be received well enough so long as people believe MK9 and SSB5 are coming.  The moment people think these are replacements, that could turn very bad. 

Also, the assumption that it's either resources go to MK9/SSB5  OR go to Metroid or F-Zero is obviously fallacious.  Nintendo has the resources and the teams behind those two games cannot be assumed to be transferable to those projects.  And besides, Nintendo needs all the above.  They can't afford to be playing either-or with major IP right now.

Wobbling got removed in Brawl. There's no chance it would be in Smash 4 if Ice Climbers were brought back. The chaingrab they had in Brawl would almost certainly be gone as well, as Dedede's got removed for Smash 4 too.

O/T: I'm in the minority here; I don't think I'd want any new characters. I've been playing the game consistently for 2+ years now and there are still a good ten or so matchups that I don't know well (though basically everyone I wanted got into Smash 4, so I'm probably biased). I'd like to see one last balance patch for the existing cast. Some new stages would be fantastic; preferably at least a couple that could be used in competitive play.

I'd also love some new costumes for the existing (non Mii) cast. Not just generic palette swaps, but have some new models for characters not in the game. Maybe have Chrom as an alt for Ike or Lucina, Prime 3 Varia Suit as an alt for Samus, BotW Link as an alt for Link...maybe even Ridley as an alt for Charizard. One thing I'd love to see but will totally never happen would be some different clothes/gear that you could customize your character in the same way you can Miis or fighters in Killer Instinct. I would pay good money to be able to play as Ganon with a tophat.

I don't understand all these people saying they'd rather have Smash 5. Would there really be a huge difference between Smash 4 with new characters, new modes, and performance/balance updates and Smash 5?

I can understand wanting new games before the 7th gen, but now it seems like it would be more efficient to run Smash Deluxe as a service and provide periodic updates to make it better instead of rebuilding an almost identical game.

Actually, I don't want much at all. Just include all the DLC, both Smash Tour and Smash Run.

I think they should keep the new stuff for Smash 5.

While it would be great to get a Smash 5, as a long-time fan of the franchise, I think we're a few years away from that. Sakurai just finished DLC back in 2015 and the base game was done in 2014. With the exception of the gap between 64 and Melee, the gaps between the other games' releases are quite long. Unless someone else is taking the helm of the franchise, I cannot see Sakurai making a turnaround that quickly, especially with what he has gone through in the latest Smash development.

Plus, its gonna be hard to go from the roster we have now to whatever takes place next. When you think of dream rosters, there's basically very few rivals to Smash 4. Cloud, Ryu, Mega Man, Pac-Man, Sonic, and Bayonetta going toe-to-toe with Mario, Link, Samus, Pikachu, Fox, DK, etc. and with the newbies varying from old school (ie, Duck Hunt, Little Mac, Palutena) to new school (ie, Corrin, Lucina, Robin, Bowser Jr., Wii Fit Trainer, Rosalina and Luma, Villager). And with the latest Smash 4 competitive major, 2ggt Civil War, showing incredible balance (ie, low-tier Link making top 3 and Capt. Falcon going runner-up), I think we're mostly set for a while.

Of course, more is great, but if Smash 5 were to come around, I do wonder if we'll be able to keep most of the roster intact, especially with the third-parties. I guess we'll see, but for now, I personally like where Smash 4 is going. It's only three years old so we may not see a new installment for a while.

Smash 5 won't be seeing the light of day until 2019 or 2020. I'm not even sure if Sakurai is any condition to make it.

Smash Deluxe is an easy port and easy money for Nintendo. Besides it's already been stated by two pretty reliable sources to be in development anyway.

Isaac :/ come on. Remake the first three games on the Switch and then release the 4th too

That, all content including DLCs from 3DS and Wii U and some other characters and stages.

MK8D fixed the multiplayer, SSB for Switch should fix the single player.

I skipped Smash because they skipped the single player content; add an adventure mode a la Subspace Emissary.
