Various sources have alluded to NPD sales figures which apparently indicate that Disney's Epic Mickey sold 1.3 million copies in the US in December 2010, whilst Gran Turismo 5 sold 565,500.
The numbers for Epic Mickey don't come directly from NPD, which doesn't tend to release specific figures, but the LA Times has cited "people familiar with the data". The Gran Turismo numbers, however, were apparently released to Industry Gamers by NPD itself.
Whilst Epic Mickey failed to make any impact on UK charts after mediocre reviews, the Wii exclusive made number 6 in NPD's North American chart for December 2010. Above it were two other Wii exclusive titles: Donkey Kong Country Returns at fifth, and Just Dance 2 in second.
Gran Turismo 5 failed to make the top ten with its December total of 565,500 - less than the 579,000 which were sold in North America during the game's first few days of release from 24-28 November.
