They need a heavy bundle or a ton of bundles this holiday season to beat 2013. Super Mario Maker provides between 20k-55k and that will pretty much lead to the gap being closed. I personally see the bundle doing 30K+ with 40K being what I want to see. it shouldn't drop off automatically either and should help it create a fairly big gap between it and 2013 before 2013's big week. After that its all about the bundles nintendo will offer.

Mhm. Beating 2013 will be extremely difficult, but not totally impossible. 

The Super Mario Maker bundle will boost sales, Star Fox will either keep the baseline steady or be a surprise hit, Animal Crossing could attract some potential buyers if they market it enough, and Genei Ibun Roku #FE will probably boost the system along the lines of Xenoblade Chronicles X, maybe more considering it has two well known brands attached to it, but it also depends on if there's a bundle or not.

What Nintendo really needs to do is make a "Best Value + Splatoon" bundle, where the console is like 6000 yen cheaper, Splatoon and maybe 1 other game is included (something that's really popular, like MK8 or Smash), and maybe an amiibo if they want. Then market it like crazy as a limited time offer and sales would go through the roof. 

I wouldn't count Genei Ibun Roku #FE out for Japan. Same for Animal Crossing Amiibo Festival, but that's more debatable. And who knows, Maybe Mario tennis Ultra Smash will be a... Smash Hit?

Amiibo Festival comes bundled with Amiibos, and is a mixture of Animal Crossing, Amiibos, and Mario Party. Nintendo literally just smashed a bunch of their things that generate ungodly amounts of money together.

Also, Mario Tennis has actually sold exceptionally well in Japan in the past.

I wouldn't count on Mario Tennis moving any hardware.

That being said, GIR#FE, Animal Crossing and Yokai Dance definitely have the potential to move a good amount of hardware if handled properly. Star Fox Zero is the true wildcard, though. It could surprise us like Splatoon (though not on the same level, obviously).

Oh yeah,I forgot about Amiibo Festival! After HHD I should know better than to underestimate a spinoff AC game (no sarcasm even though it sounds like it). #FE should sell okay but I have my doubts about that pushing systems, same for Mario Tennis. 

Agreed, Splatoon is selling so well that a Bundle is long overdue. Would be nice if it had a unique, multicolored (as if inked by different guns) case as well

Speaking of unique cases, it's a bit sad that this tradition died away. The many colors of the Gamecube or the N64 where always interesting and an eye-catcher compard to the bland black-or-white cases you see all the time. I'd wish they made a green Link special edition when Zelda Wii U gets released, complete with the game, WWHD, and digital copies of Twilight Princess, Skyward sword and all the NES-N64 Zelda games from the VC preinstalled; an updated copy of the Hyrule Historia, all Zelda-themed Amiibo and maybe some other goodies. That would be a Zelda collector's edition worth the name - and probably a lot of sales, even if priced at a prohibitive 500-600$

Agreed. If they did more special editions for the Wii U like they do with the 3DS, I believe it would sell more. Even if it's just a bit. 

That Zelda bundle would be a dream come true for many. It's just a shame that it won't happen, lol. Well, a limited edition console might, but not all the stuff with it, unfortunately.

Updated! Wii U increasing week on week and the gap between it in 2014 is growing!

Well, looks like 11k is the new baseline for the Wii U in Japan. Quite an improvement from what we had the last years
