Nintendo expects to sell 10.5 million Wii and Wii U consoles worldwide during the fiscal year ending March 2013, it's revealed.

The figure includes total forecast sales for both consoles between April 2012 and March 2013.

But considering the Wii's flagging sales, the majority of those sales are expected to be of the upcoming Wii U console.

Wii only managed to sell 710,000 units worldwide between April and June 2012, compared to 1,560,000 during the same time-frame in the previous year.

Based on the assumption that Wii sales will continue to fall, predicts that Nintendo hopes to sell around 7.5m Wii Us before April 2012 - this is based on a crude estimate of 3 million Wii consoles sold in the financial year.

Wii U is due to launch in Japan, the US and Europe "at the end of the calendar year".
