Splatoon 2 at the moment, because it's the closest to coming out and we know the most about it. It's exactly what I wanted as a sequel to a game that I put 400+ hours into. Subtle, but definite graphical improvements, new maps, weapons, specials, gear, customization options, and presumably a single-player story mode too, while still keeping everything that was great about the original.
Then Super Mario Odyssey because it's confirmed to be a sandbox Mario again finally, after all these years, and looks great so far. I just want to know more about it. Are we collecting stars in each level? What are those purple triangles? What's the 'health' bar look like...akin to 64/Sunshine, or less segments like Galaxy, or big/small Mario like 2D/3D Land/World? How many sandbox worlds will there be?
And then, the game that will likely end up being my most anticipated game (and possibly even surpassing Zelda, though at the moment I'm not as big of a fan of its 'look' as I am of BotW's PERFECTLY chosen style for Zelda) is Xenoblade Chronicles 2. We just saw very little of it from the teaser trailer. I'm assuming a full trailer will come by E3, and hopefully even gameplay footage from Treehouse. I don't expect it to actually make a 2017 launch though (at least outside of Japan). I wouldn't be surprised if it winds up being a Spring 2018 game in NA and EU. That being said, I do like that it looks more bright and colorful and fantasy-oriented like the original rather than the more realistic, gritty sci-fi stylizing of XCX (I LOVED XCX though). The music team looks good and sounded good in the trailer. The world looks nice, though we need to see more. I need to see the battle system (hoping it continues the great one from XC and XCX), and know a little more about the story. I hope the story and characters are more prominent, epic, and integrated into the exploration and story (like the original, rather than XCX's chapters). So yeah, definitely excited, but just need to know a lot more.
I'm excited for Fire Emblem 2018 as well, as I got into the series with Awakening and then Fates, and hope it continues what was great about those games, but just goes HD and has even higher production values than the already great ones those games had (for 3DS, the character art and anime-style cutscenes and music were all fantastic).
At the moment, and especially after the most recent trailer, it's pretty difficult to think about any game other than Breath of the Wild. Man, I can't wait. 40 days and counting!
