Graphical improvement is pretty much a given and Nintendo is pretty damn good at making the most of what they have. To this day, I think Super Mario Galaxy looks better than a good chunk of what was on the PS3 and 360. Yeah, there are some games where you can tell that the hardware is dated. - Tears of the Kingdom and Xenoblade Chronicles 3, as fantastic as both those games are, there were definitely points where you could tell - "Yeah, the Switch is getting old, we're just about ready for an upgrade." But by and large, Switch games, especially 1st party Switch games, comfortably meet the standards, mine at least, of how a game should 'look'. Which is to say, pleasing to the eye and as long as the game is fun and playable, then graphics aren't really that much of a concern for me.
The main things I'm looking for are on the technical side. Loading times, processing, etc. That's usually what I refer to in my "ready for an upgrade" statement. Because as much fun as I had in TOTK and XC3, one too many times I can remember just being immersed in the game and world and my immersion is abruptly interrupted by sudden pop-up or late loading of certain textures or world objects where I'm like "WOAH! Where did THAT come from?!?" And in other games or even the eShop, the loading times are a bit too long for my liking.
I can take or leave 4K, if Switch 2 can give me a solid, consistent 1080/60 experience (720/60 when undocked) w/ fast loading times and little to no pop-up. I'd be satisfied.
As far as gameplay content goes?
Zelda: Go back to more of the traditional 3D formula in the main game. You can still have the open world similar to BOTW and TOTK, but don't make them immediately accessible from the jump, because it's really hard to tell a cohesive story that way. Tears of the Kingdom, I felt tried to do more of that, but still clung a little too much to the Breath of the Wild openness and exploration and as a result, the storytelling suffered. For example, when finding the dragon's tears became available, I immediately made that a priority, and by the time I got the final tear, I had only completed one of the dungeons or so and anytime I would hear/see someone go...
I would scratch my head or roll my eyes and say...
And the more it happened, the more it took me out of it. If they had held off on the tear collecting until AFTER you completed the dungeons, or only made some of them accessible/unlockable after each dungeon, it would have made for a more emotional investment and a bigger impact when you finally DO realize what happened.
The open world can still be there, but have it take a back seat to incorporate more of the old school 3D elements that we had from Ocarina of Time to Skyward Sword - More emphasis on dungeons, story-telling, and character development. And the more the story progresses, the more of the world you unlock.
