Lemme answer that real quick; amiibo-ships. Seems like the smarter thing to do, Ninty should just kill the Wii U outright and put all of their efforts in those useless toys, pretty sure they'd be fine that way.

Agreed.  It is really the level of quality and knowing the big hitters Capcom have on a Nintendo console I doubt gamers who liked Capcom games before won't buy those games in the Wii u

I mean, I think it's too late for the Wii U, and it would be wasted effort on Nintendo's part to put them on it. But it would be just the kickstart the NX needs to take off. But only alongside a big western aquisition. They need to be able to pump out new IP like Horison: Zero Dawn or Recore that immediately appeal to gamers in the west that arent interested in Nintendo's line up. The Capcom 5 is great, and huge, but is not enough by itself. They need a solid western branch as well, whether it through an aquisition of IP like Square did with Eidos, acquisition of studios to create new western IP, or both. Either way, they need both.

Nintendo is Disney. Capcom is their Marvel, with Nintendo vs. Capcom as their Avengers. They need a Star Wars.

Metroid Prime Federation Force NHL Hockey with EA ;)

We still also have no info on that Tantalus game.

Bowser will be playable in that Lego multiverse game. And there will obviously be a Lego Bowser amiibo.

By forcefully trying to limit their audience and essentially leaving them with an audience that outside of the handheld space has had no exposure to their games in ages. Capcom is way too big for Nintendo to carry them.

Capcom, Platinum Games and Monolith Soft are good options for Nintendo. Having all three in terms of some deal would help them out. Acquiring Atlus from SEGA would also help; Armor Project no less.

I think Ace Combat U is a good idea.
Fire Emblem fighters use swords, if you are thinking of a crossover it should be with Soul Calibur, but already Namco is making a 3D Fighter for Wii U (Pokken)

If something like that were to happen, much of that audience would move to NX. That's the point. It wouldn't be the Nintendo audience buying Capcom games - it would be the Capcom audience buying the NX. And across five major franchises, that audience would be massive. Capcom isn't even close to being too big for Nintendo to carry. That's like saying that Marvel was too big for Disney to carry, yet here we are.

Again, it's no different than the Street Fighter V deal. Only way, way bigger. And with the insane amounts of money Nintendo would need to fork over to get such a deal, Capcom would walk away more than fine on the other side. Nintendo vs. Capcom would sell massively on brand power alone. Monster Hunter is already exclusive. Mega Man would be published by Nintendo and easily sell on the NX even before the crossover of audiences, especially if it was just a Tropical Freeze-tier 2D platformer using the Smash 4 artstyle to feel distinctly "Nintendo."

That just leaves a Resident Evil game and a Devil May Cry game which would be the only two "significant" exclusives of the bunch. Devil May Cry and Resident Evil could either go the direct sequel way, being Devil May Cry 5 and Resident Evil 7, or they could go into a "spin off" direction by having Devil May Cry x Bayonetta as the DMC rep and another "Revelations"-like spin off be the Resident Evil Rep.

With the latter, Capcom could still make Devil May Cry 5 and Resi7 multiplatform, effectively meaning that the exclusivity deal changes absolutely nothing about how they operate, aside from giving Nintendo a significant exclusive line up.

Nintendo vs. Capcom - Exclusive thanks to the IP.

Monster Hunter NX - Exclusive via status quo

Mega Man - Exclusive via developement support. Possibly even have Retro make it.

Devil May Cry x Bayonetta - Exclusivity via Platinum alliance

Resident Evil Revelations-like spin off - Exclusivity via non commitment, just like what was the case with Revelations, since its not a numbered game like Resi4 was.

And Ninyendo would be publishing/ financially influential in all of these. The first three are extremely low risk. All guaranteed to sell above a million, and frankly, the first two would sell above two million easily. The last two, in a desperate struggle, would at least have the potential to hit 1m based solely on the power of the IP and the installed base potential of a platform like the NX with a unified installed base between the handheld and console. But they would likely sell closer to 2m, as even Resi4 on the GCN managed to err towards 2m.

The deal would be fantastic for both. Fantastic for Nintendo in the attempt to cultivate a hardcore audience, and fantastic for Capcom in that they'd make a shit ton of money.
