For me main reason on buying WiiU was MonsterHunter3 ultimate.
I knew that I'll get X, Bayonetta, SmashU and MarioKart and ZeldaU eventually, they was an important reasons too.
But a lot of games I have on WiiU now are keep me satisfied and happy - from Mfrio3dWorld to DeusEx.
Only game taking me out of WiiU is Diablo3ROS on PC now.

I was satisfied with my day 1 purchase with ZombieU, it was the drought afterwards that rustled my jimmies.
Still satisfied with the console, just wish i hadn't had to wait so long for the major titles.

A good 3D Mario (check)
A good 2D Mario (check)
A good DKC (check)
A good Mario Kart (soon to be checked)
A good Smash Bros (soon to be checked)
A good Zelda (It's coming)
A good Metroid (2015?)

Some type of console Pokemon (Pokken Fighters 2015?)

The obligatory Wii Sports/Fit/Party sequels/updates (required from a  console with "Wii" in the name) -- done. 

Are the main pillars for any Nintendo home console I think, and in that regard, Wii U almost has put in all its work.

Then Nintendo generally has some "supporting" titles and I think Nintendo is doing OK in that regard too ...

X, Bayonetta 2, Pikmin 3, Wonderful 101, Fatal Frame (localize it NOA you dummies), Hyrule Warriors, SMT x Fire Emblem, Yarn Yoshi, LEGO City, seems to be a decent number of support titles. Nintendo Land as well of course. 

I think Wii U honestly will overtake the GameCube's lifetime library output from Nintendo 1st/2nd party by the end of 2015 pretty comfortably, especially if Zelda U is better than Wind Waker for GameCube.

Zelda U!

But will be nice if we get Starfox for Wii U and another 3D Mario game, and few N64/GC HD remakes and much more VC titles.

Paper Mario and Zelda U are the only ones the console needs. Honestly everything else would just be a bonus.

Although I do hope miyamoto's new IP is good.

You mean satisfied with the support so Nintendo can go sink themselves on a rushed dud? I wont be satisfied with only what i know now is coming out. i will be satisfied with 3 more years of support. I wont buy the next Nintendo hardware otherwise.

As for current satisfaction, i am pretty happy with Sonic lost world, Sonic boom, MK8 and X. Theres more games coming out that i want, but those make me pretty excited to have a Wii U.

Merely satisfied.
Whats announced so far and what we already have

I'm already satisfied. X alone should be worth the purchase, and the next Zelda should make it outstanding. What I'd really like to see is a couple of good surprises over the next few years, some cool new ip's or titles. I'd also like to see COD support at least through this year so I don't have to pay for online games, and a Mistwalker RPG. That would be incredible. After this year or next, I'll be ready for a new system or PC.

Got a white WiiU for 200 bucks (also own a black WiiU that I got for free) already am satisfied with the current library. Mk8, Smash, X, Bayonetta2, Hyrule Warriors and one day Zelda will make it even better. (plus some other unannounced games)

Since real gamers dont just play 2 genres (shooters and sports) I have at least 1 game for every month the WiiU is out so far.

If it keeps going that way I have at least 24 good games when the WiiU is 2 years old. (which is actually quite impressive)

Most of my games are Nintendo games but I also have Rayman, ZombiU, Darksiders2, TekkenTag2, SonicRacing etc. So if the game is actually a great port or exclusive and is not made by EA/Activision. I buy it.
If a game is sub 28fps ocasionally I just ignore it since its unplayable for me. (AssCreed or Batman)

Monolith Soft's "X" and the next "The Legend of Zelda" game. Along with Smash Bros. and Mario Kart 8 which we know are already coming this year.
