Nintendo's first quarter financials reveal a mixed bag of news for the Wii U, as lifetime sales for the console edged past the 10 million mark but fell year-on-year.

For the three month period ending June 30, the company sold 470,000 units of the Wii U compared with 510,000 last year. In terms of breakdown, sales in Japan shot up from 60,000 last year to 150,000 this year, though the opposite was true in the rest of the world.

In the US sales fell from 280,000 last year to just 190,000 in this period. Similarly sales in other territories went from 170,000 to 130,000.

This drop is despite the launch of Splatoon, which has sold 1.62 million units despite launching at the end of May. Wii U software sold a total of 4.55 million units worldwide.

The 3DS did much better, however, with the hardware family selling 1.01 million units in Q1 compared with 820,000 in the same window last year. 3DS games sales fell from 8.57 million to 7.92 million.

Amiibo sales were referred to as "favourable" although no solid numbers were given. We heard back in May that 10.5 million have been shipped to retailers.

All this combines to see the company make an ¥8.3 billion net profit ($67 million) up from a ¥9.9 billion loss in the same period last year. Revenue hit ¥90.2 billion ($729 million), which is a 21 percent increase year-on-year, with ¥65 billion of that amount coming from overseas markets.

In terms of the year ahead, Nintendo highlights new Amiibo releases as well as big releases including Animal Crossing: Happy Home Designer, The Legend of Zelda: Tri Force Heroes and Pokemon Super Mystery Dungeon for the 3DS, and Yoshi's Woolly World and Super Mario Maker for the Wii U. A smartphone app is also coming before the end of 2015.
