Let's see what's announced/likely for 2014:
- Donkey Kong Country: Tropical Freeze
- Mario Kart 8
- Super Smash Bros 4
- Bayonetta 2
- Yarn Yoshi
- X
- Watch Dogs
- Lego Games
Actually, considering how I only buy about 5 to 10 retail console games a year (on account of also buying handheld and PC games), so long as Nintendo doesn't delay anything, or at least replaces delayed titles with other games. I'm fine for their retail software.
Other things I'd like would include more downloadable games, including Virtual Console, Indie and/or other non-retail titles, a unified account system with the 3DS, maybe a software update or two for speed and reliability, and... actually, that's about it. I'm mostly satisfied with my current Wii U experience, save for the supply of games. And that seems to be getting largely resolved, so...
