Basically there's three categories of Wii U software: 

1.) Decent to Good Sales: 2D Mario, 3D Mario, Smash Brothers (Mario Fighting), Mario Kart are the main things that will sell on the Wii U, with some room left over for Zelda. Future home of: Mario Party 10, Mario Maker, Legend of Zelda U. 

2.) Poor/Low Sales: Donkey Kong Country, Pikmin 3, Wii Fit, Sonic Colors, Rayman didn't sell great. Wii Party U got saved by being bundled in Japan for a while. Future home to: Yarn Yoshi, Captain Toad, Splatoon, Xenoblade. 

3. ) Bomba Sales: Bayonetta, Call of Duty, Batman, Fatal Frame, Wonderful 101, Assassin's Creed, Need For Speed, Wii Sports Club, etc. are full-on bombs. Future home to: Devil's Third, Project: Cars (if that actually even comes out). 

"Nobody expected Ubisoft’s Watch Dogs to do well, but 14th is even lower than anyone would have thought."

Pretty sure this isn't true. I was even surprised when there was a Gaf thread for people asking info about it, and people in the thread actually interested in it, and not the usual troll responses like from that ninjablade guy or something.

Project CARS will fail just as hard on the wii u. It too is not releasing at the same time as the other versions.

Well, looks like no rest for the weary. Wii U's struggles will continue.

This prediction deserves to be bolded and its own thread (unless it gets a bundle).

It's a safe prediction. IMO Splatoon won't sell anything great. 

The online community, even the online Nintendo community, is not the general Wii U buying base, if it was Bayonetta 2 would be a 1-2 million seller. 

I think Zombi U also is monstrously overtracked by VGChartz. If it sold anywhere near what they claim, Ubi Soft would've made a sequel IMO. Kinda sad seeing it at the store the other day, they've now marked it down from even $19.99 to $14.99, lol. They should just give them away for free to anyone who buys a Wii U. 

EA and Ubisoft are real pricks to deal with and are full of hypocrisy but you can't deny that having them support your system is good for sales. I am a dedicated Wii U fan and although I personally wouldn't buy too many of their games the Wii U would have a greater install base if those 2 companies supported it. When I say support I mean REAL support not crappy ports from 360 games.
The Wii U looks like ending this year on about 9 million consoles sold, whether that is enough to entice 3rd party support remains to be seen but if they continue to get almost no new 3rd party devs on board 2015 could make for a pretty grim year with Nintendo. When you consider that if Nintendo follow their usual strategy of 6 years approx. between consoles it could be 2018 before a new home console is around and not even the amazing games they produce themselves will save them if 4-5 AAA games a year are released on the system.

"TLOUR is a year late port of a game on the same platform holder and sold 2M, check."

TLOUR is a highly acclaimed Playstation exclusive that won multiple awards remastered for Sony's new console which is selling the best out of all other consoles.

GTAV is one of the best selling games of last gen, winning multiple awards, one of the most hyped, and being one of the industry's most celebrated franchsies being remastered for new gen consoles with various graphical enhancements once again sells well.

"Bayoneta 2 is considered a sucess on WiiU by selling less than 500k, check."

I've never seen anyone say this, some quotes please?  It would also depend on the budget and how much Nintendo needs to sell to become successful.  Besides I think Bayo 2 was simply to bolster their lineup and nothing more.  Nintendo has a history of funding these types of games which are usually not successful, but diversify their games lineup.

"AC and Destiny sells on the 5-10M window. WD as well, check."

Assassin's Creed is one of the biggest franchises of last gen, and Destiny and Watch Dogs are two of the most hyped and marketed franchises of this gen.

"If game launched along other versions it would still be inferior and people would still buy in other systems if they had them. "

Be inferior how exactly?  It'd be inferior to current gen versions in graphics surely, but they could have made an effort on the gamepad features like they promised, and be superior in some ways, gameplay wise.

"when we know it would sell the same anyway?"

I'd like to see all the people who can guess hypothetical situations with 100% accuracy.  Maybe they have the ability to travel to these alternate worlds.  I could make use of that.

No, we don't know how badly it would sell on Wii U, and it would sell badly.  But I'm pretty sure it would not have sold as badly as it is now.  Releasing a version of a game that came out on every platform 6 months prior, full price, looks about on par with last gen versions. with no additional features, minus some lazy gamepad integration with no marketing, I would assume, would have an effect on sales.

Edited because it is coming off a bit too snarky.

Does the writing on the wall have to be spelled out in even bigger letters? Third parties are done with Wii U unless it's LEGO/shovel kidsware junk. 

Wii U hasn't proven it can sell anything outside of Mario/Zelda worth a damn, so until it does, I don't give it the benefit of the doubt. 

DKC and Bayonetta and Pikmin are all great games too, so to me it indicates something is very wrong with that audience base. 

Nintendo basically has lost all audience diversity on their console base by losing those people to Playstation/XBox. The only people left en masse are the Mario fanatics who like a little Zelda on the side. 

I get it that the online Nintendo community makes a stink about this and feels slighted, but the cold, hard reality is you're simply not that big of an audience. 

The people who buy Nintendo consoles who want to also play games like Watch Dogs, Call of Duty, and other violent/action based core IP are a very, very, very small minority. 

If you were running EA or Ubi Soft as a business with your own money on the line, you wouldn't support the Wii U either. It's nothing personal, this is a business, plain and simple. 

Nintendo lost all the people that would buy these types of games probably years ago to Sony/MS, it just kind of got glossed over because soccer moms were buying Wii Sports/Fit like crazy for a couple of years before they discovered the almighty smartphone. 

Nintendo as a brand just is a full-on non-factor for these types of games. The last time Nintendo was relevant to college age/adult male gamers in a big way was with GoldenEye like 16 years ago (!). A lot of the kids who play Call of Duty today weren't even born yet, lol. Nintendo is completely removed from having a prayer in selling these types of games.
