The place Nintendo should go from here is back in time a couple weeks and make the deluxe bundle with Nintendoland and Mario 3D World a Black Friday deal everywhere for $250 with a store gift card, instead of it being $250 at Target in a week. I think at the right price, they could have done very well this holiday season. The lineup at this point is good, especially if it's a second system like it will be for most people. But while the deals on the X-Box One were really good and it sounds like moved a ton of consoles, Nintendo just let the Wii U sit around at full price. Maybe Smash and Amiibo helped them sell a good amount of consoles but the lack of deals this holiday season seems like it was a missed opportunity.
As far as what I'd like to see, Animal Crossing is at the top of the list. It's the perfect game for having off TV play. I'm excited about several of the games they've already announced, just supplement the list with a few surprises and maybe some collaborations with other companies, like they did with Hyrule Warriors, to add to the list of releases and I'll be happy. I know it'll never happen but I'd love to see a Mario HD collection with Mario 64, Sunshine, and the Galaxy games.
