Nintendo recently announced that it would be revising sales figures for 2014 following lower than expected sales of the Nintendo Wii U. The company had hoped to sell 9m units by the end of the year but now believes it's on track to sell just 2.8m.
Despite the company's now predicted loss of £200m the Nintendo 3DS remains one of the best-selling handheld games consoles in the world thanks to predicted sales of 13.5m.
