Wii U will never beat PS Vita! (real sales)

[Salnax]

I don't see how the Vita can stay ahead of the Wii U forever.

Even if Sony has shipped a lot more Vita units than VGChartz has shown sold, it's been shown before that Sony ships more units prior to sales than Nintendo does. The Vita being undertracked here is likely, but the sales difference between the Vita and Wii U is probably much higher than you are saying.

I'm going to look at the Wii U and Vita in the "Four Regions" over the rest of their lives, based on known info and what I hope is reasonable speculation.

North America is already a much bigger Wii U region than Vita region. 2014's numbers could easily be the peak for the Wii U there, but even then, the legs of prior Mario Kart and Super Smash Bros iterations combined with games like Mario Party, Zelda, and Mario Maker would keep the decline from being too great. Though the Vita is getting a number of smaller games, these have not helped the Vita sell well in the past, and retail support seems to be declining if anything. I expect the Wii U to outsell the Vita in North America by roughly 1 million in 2015.

Europe saw Wii U sales rise drastically and Vita sales plummet in 2014. Otherwise, the same basic problems plague the Vita here, so let's skip to Japan.

Japan is the Vita's strongest major region, especially compared to the Wii U, but I do not think the Vita will do that well in Japan alone. Vita sales declined in 2014 despite the recent new model, and the software increase can be partially attributed to the micro-console version of the Vita. As for 2015's Vita lineup, it does not impress. God Eater 2: Rage Burst is definitely something to watch, and can easily pass half a million in Japan, but has to compete with the PS4 version. Sword Art Online's fanbase is likely on the Vita already thanks to Hollow Fragment, Pirate Warriors 2 wasn't that big on the Vita, and Dancing all Night is a music spinoff to a game that is only getting older.

"Rest of World" has purchased 1.13 million Vita units. This will rise, but I doubt the Vita in these places will be proportionately as popular as the Vita, especially given how mobile gaming continues to grow.
