Could be, but when Wii U price went from:
2012 - 30.000 yen (31.500 tax included)
2013 - 31.238 yen (32.800 tax included)
2014 - 32.800 yen (35.424 tax included)
You should realize that something is wrong. Nintendo seems it's not.
The price is increasing every year. Wii U is more expensive now than never.
You can say that now includes a game (Mario Kart 8), compared to 2012.
But if we compare with 2013 that included 2 games, and 30 days Karaoke for free, making you save 16.000 yen. This year's bundle is not attractive.
I think this shows that Nintendo's strategy has never been about "saving" the Wii U by doing whatever it takes to move more units.
They seem to be focusing instead on maximizing the amount of money they get from those consumers who are still interested in their products.
