Star Fox or some Amiibo hub game.

Could be an Animal Crossing spin-off like title like the 3DS is getting, but I think proper Animal Crossing is being saved now for the next handheld.

Nintendo needs to be a little smarter from here on out on how they manage their IP, because they will need to make sure they have enough content early in the NX's lifecycle. If it's another case of a lack of software early on while Nintendo spent IP like Animal Crossing on a failing Wii U that netted them nothing in the long run they have no one to blame but themselves for poor asset management.

Guys...it'll be a remaster of Super Mario Sunshine...we all know this.

In all seriousness, I think it's safe to bet either a Sunshine HD or Galaxy 1/2 HD will come out this year. My money is on a Galaxy pack, since that would just need an HD makeover to look amazing. Sunshine would need to be a remake from the ground up, not just an HD remaster, or it will look crappy even with HD resolution. Obviously not as their big Holiday release though.

It's also possible they sent a Twilight Princess HD remaster into rush development for this Holiday upon realization of the Zelda U delay. Wouldn't surprise me.

At this rate Mario Maker.

I don't know if they will have Xenoblade Chronicles X localized in time, I have doubts about Star Fox especially given how little we've seen of it much like the Wii U Zelda which has already been pushed back. Unless they announce some spectacular at E3, its Mario Maker or bust. Maybe a Wii U port of the Pokken arcade fighting game, but despite Smash Bros being successful that fits more into the niche of traditional fighters.

Gonna say Star Fox or Xenoblade X, Mario Maker comes out September though

Star Fox might be delayed for then but I doubt it.

It will be SMT x FE in Japan and maybe another.

For the rest of the world it will most likely be an unannounced game. Animal Crossing U hopefully?

In Japan it seems that SMTXFire emblem might be their holiday title but who knows?

looks like we'll be getting XCX sooner than StarFox, so prob XCX July-September and StarFox November.

Other than this, I'm sure that we'll see another huge title hit the year that is still unannounced.

This.

I think Sunshine is more likely for an HD re-make than Galaxy.  For one thing, Sunshine needs an HD re-make way more than Galaxy.  Galaxy still looks pretty amazing, IMO, while Sunshine is definitely showing it's age (there are also some broken levels in Sunshine that could definitely benefit from some re-work).  I also think that if Splatoon turns out to be a hit it might boost demand for Sunshine just because the two games have a similar concept and the single player in Splatoon might leave people wanting more.

Hopefully Starfox, but now I am not holding out any hope. My plans to get a Wii U though haven't fallen short though. Just need one more big game to take the dive this year and Splatoon might be it.
