For things that I'd like to see ported from Wii U, both Wind Waker HD and Twilight Princess HD would be nice. Been in the mood to replay those, and a combo pack wouldn't be unreasonable since they're not a new remaster in the way Skyward Sword was.
Paper Mario: Color Splash is one of my port announcement pipe dreams, but I bet they don't think it's worth it given the reception it got and how it used the Gamepad to paint cards in battle. I'm not going to claim it's a """good""" Paper Mario, but I enjoyed my time with the game (more than I can say for Sticker Star). My Wii U Gamepad holds the worst charge, so any plans I had to replay Color Splash are dashed when I remember that.
Anyway, my top hope is a Fire Emblem announcement. Gimme Genealogy of the Holy War remake. A new game would also be nice. Also hoping that Tomodachi Life gets a Switch game. Miitopia doesn't scratch the same itch.
