Nice list. I too believe Nintendo will manage to deliver 1 retail game for WiiU per month starting calendar year 2015. Of cource, my list looks a tiny bit different:

2015: January: - Mario vs Donkey Kong (This seems to be very far along, but doesn't look like a retail game)
2015: February: - Yoshis Woolly World (This also looks to be very far along)
2015: March - Mario Party 10 (This looks to be almost complete and since recent console Mario Parties have released in March)
2015: April - Mario Maker (Looked far along but unsure if they're planning on this being a retail release)
2015: May - Kirby and the Rainbow Curse (Also looked far along from what i've seen)
2015: June - Splatoon (Looked to be well under way and should be ready in time for E3)
2015: July - Super Mario Sunshine HD (I'm pretty sure this is the rumoured remaster and it makes sense to release it in the summer)
2015: August - Fatal Frame (Since Nintendo needs games i'm sure they'll be willing to translate this for a western release)
2015: September: - Xenoblade Chronicles X (Ifelt it too could need some polishing, so it makes sense to release it 2nd half 2015)
2015: October: - Devil's Third (I place it second half 2015 since it looked rough around the edges judging from E3 build)
2015: November: - Legend of Zelda (Should release the week leading up to thanksgiving)
2015: December: - SMT x Fire Emblem (It has prolly been in development for quite some time and should be ready by the end of 2015)

Of cource there is the question of what games Next Level, Monster, and Retro is working on. It could be some of their games could be ready for a second half 2015 release.

I dont believe StarFox will be ready in 2015. We already know Kamiya is working with MS now so there prolly wont be any project by the W101 team launching on WiiU anytime soon.

What other Nintendo teams and affiliates could have something ready for 2015? Bottom line: They can do it if not every game is supposed to be big budget.

big blogbuster first party AAA game? no
just a game every month? yes

Maybe. It really depends on the status of SMTxFE and whether or not Fatal Frame V gets localized. Also, I don't think it'll be strictly one game per month, but rather on average one game a month. I'll list some predictions for release dates below.

• January: nothing
• February: Yoshi's Woolly World
• March: nothing
• April: Mario Maker
• May: Splatoon, Mario Party 10
• June: Kirby and the Rainbow Curse
• July: Fatal Frame V
• August: Devil's Third
• September: Xenoblade Chronicles X, rumored remaster
• October: Shin Megami Tensei X Fire Emblem, Star Fox
• November: The Legend of Zelda
• December: nothing

I thought I read Splatoon was promised  Q1 but maybe it was " first half of 2015"

Apparantly Starfox has been promised whitin a year:

Fatal Frame IS a guess but I understand there is a FF movie coming:

Zelda U/Galaxy. There is a rumor that there will be a BIG remake in 2015 (see OP). Yet Zelda is also promised 2015 and all we have seen so far is a tech "movie" with no gameplay shown.

YES. THAT WOULD BE AWESOME.

It is VERY wishful. Nice to see that you have commented the whole list. It was not made for serious at first but as I get more comments about it I start to believe in it myself.

2014-2015 are at least possible

2016+ is all complete guesswork

let's hope!

Plus, 3D Metroid for late 2017 would mean a fucking decade without a Prime-like game!

Alright, I've placed lots of thought, and now I'm ready to make my own list of 2015-ready games, worst-case scenario edition!

January: None. Take note that people are still coming of the holiday rush, so I don't think it makes sense for them to release anything at this point. However, this is the perfect time to start revealing games and getting people on the hype train.

February: Mario vs. Donkey Kong (Wii U). I doubt this being a capable retail release, but time will tell.

March: Mario Party 10. It seems nearly complete, so it makes sense for them to release in...Spring.

April: Mario Maker. Whether this becomes a retail release is still up in the air. I expect delays if they wish to flesh this out with additional stage styles.

Kirby and The Rainbow Curse. At E3, this was already a fleshed-out-looking title, and they already have a predecent for the gameplay.

May: Yoshi's Wooly World. I expect it to play second-fiddle to the big release this month...

Splatoon. Expect some hype being built for this game. Million-seller for sure, unless they screw it up royally.

June: None. Nintendo will focus on the 3DS's successes (and its successor, perhaps) for this month.

July: I don't expect any releases if Nintendo doesn't bring over Fatal Frame 5.

From this point on, I will disregard the presence of unannounced titles. That means that I recognize that Nintendo can come up with a bombshell in 12 months.

August: Devil's Third. This is the perfect time to release this game. No joke. I have a wide release window, though. I expect this to go anywhere from August to November.

September: No releases. I'm betting Persona 5 will release on PS3 this month as a sort-of swansong.

October: Xenoblade X. Of course, it'll be lost in the Persona hype, but...

Shin Megami Tensei x Fire Emblem. This will capitalize, ever so slightly, on the Persona effect.

November: Zelda U. The Wii U cannot go out without a must-have release for this year.

December: Starfox U. Wishful thinking, I know, but Nintendo absolutely has to take advantage of this opportunity. Take note that they had the engine ready for E3, alpha build, at least. I say sixteen months is enough time for themk since Miyamoto has the gameplay down. Disclaimer: This is if Miyamoto decides not to include his two "projects" in Starfox U, in which case it'll be ready for mid-2016.
