-Launching of new account system and services like My Nintendo.

-Launching of firsts mobile games.

-Expanding the use of their IPs (for instance Nintendo theme park).

-Launch of biggest and probably most anticipated Nintendo game ever, Zelda U.

-Revealing and (and very likely) launch of completely new unified NX platform.

2016 will be huge for Nintendo, and probably one of the most important year in company's history, especially after faile with Wii U.

Okay... Seriously? Talking about the NX releasing 2016? Please wait to say that until they confirm it. Seriously.

They won't launch NX in 2016 (maybe) but they will reveal it in E3 2016, definitely

Nintendo will say release date when they revile NX next year, but all points that NX is coming next years, and that's widely accepted opinion.

I aded "very likely" in OP.

So what's the Wii U 2016 lineup, or do Nintendo die hard fans like seeing the company lose money, some fans they are.

Well, I hope the NX is coming next year and I hope Nintendo implements Achievements in their games.

I can count 6 big titles coming to wii u in 2016 atm

And because Kamishima said "he acknowledges the Wii U’s problems, but says the company intends to keep making software for the console", so more game will be reveal in next Nintendo Direct, I think 

More like the most risky year. Remember back in Xbox conference in 2013 ? or PlayStation conference in 2006 ? It pretty much changed everything.
Launching a WHOLE new product will always be risky.

Better hope so, 6 in twelve months, no wonder the system is in trouble. 

For now, Wii U 2016 lineup looks something like this, Zelda TP HD, Star Fox Zero, Mario and Sonic at the Olympic Games, Pokken Tournament, Fire Emblem and Shin Megami Tensei, Zelda U, and there will be probably one or two more new games. Not bad when consider that NX will probably be launched in same year.
