If it's coming out this year, I think they can get away with launching with just Mario Wonder and a few third-party games that you wouldn't see on Switch. However, I think they can easily slot in another first-party launch that can show off Redrakted's power; Nintendo usually launches their systems with two games, anyway.
I agree with the idea that Nintendo may have multiple launch titles for Switch 2 targeting different market segments, and that one of them could be a cross-gen game if the other game is more of a graphical showcase.
However, it doesn't make sense to me that Nintendo would announce Mario Wonder for Nintendo Switch if they're planning to re-announce it as a showcase title only a few weeks later.
For me, the combination of the announcement context, launch date and profile of Mario Wonder doesn't make sense if Nintendo are planning an imminent Switch 2 reveal for later this year.
That said, again, I'd be very happy to be wrong.
And everyone has the Switch 1 that’s why a game like a brand new Mario 3D is not realistic for Switch 2 launch day, Nintendo can keep it steady with other exclusives that would demonstrate the power of the console meanwhile
Nintendo have a balancing act - the Switch 1 will offer sales now, but if there are no exclusives for Switch 2, then there's less incentive to upgrade. I do think they need something to
sell the idea of upgrading, which is easier with a desirable exclusive that clearly couldn't offer the same experience on Switch 1.
A game like a 3D Mario is an evergreen that would continue selling as more and more people get Switch 2s. It would, over time, take advantage of a growing Switch 2 launch base, and, through selling consoles, increase the available market for other Switch 2 games. I wouldn't assume that it's sales would be kneecapped to the small initial install base.
That doesn't mean it's the only possible launch title - it's just that it seems a reasonable guess.
Following this premise: if Nintendo wants to go for a cross-gen approach with something like MP4, but at the same time, they want people to look at the game running on better hardware and convince them to hop on the new platform, how exactly would they do that?
IMO it's not as easy as just "crank up the graphics on the switch 2 release" because even drake has it's limits. Take metroid prime remastered for instance: on drake they could probably do proper beam lighting, 4k with DLSS or even 1440, fancy particles and fancier lighting overall. But considering how GOOD prime remastered already looks on switch, would the gamer looking at comparisons even care enough to justify buying drake?
My point is: to get to a level of enough of a difference nintendo would've to really make the basic switch MP4 experience miserable. Which I don't think they would considering where their audience is right now (and where they'll be even 2-3+ years after drake launches).
Something like patching a game like wolfenstein, the witcher 3 or doom for drake with multiple enhancements would be completely different. But the problem here is that nintendo consoles sell because of first party titles, but most first party titles on switch are 'good enough' for the average nintendo gamer.
That's why I think they will rely on a new gimmick this time. And that gimmick is better AR and/or VR. Because honestly, they could easily do it with drake and it's about time.
TBH, this is why I don't think Metroid Prime 4 is the most likely big launch game, at least so long as it remains a Switch 1 / cross-gen game. It'd be fantastic to round out a launch window, but I don't see it as being The Game.
