Nintendo's forthcoming New Super Mario Bros. Wii will be the biggest selling game of 2009, and is likely to shift over 15 million units during its lifetime.
That's the prediction of Jesse Divnich at Electronic Entertainment Design and Research, who believes the family game can outsell the Xbox 360 version of Activision's Call of Duty: Modern Warfare 2 by the end of the year.
He anticipates Nintendo sold 635,000 Wii consoles during October after being outsold by the PlayStation 3 the previous month, with DS sales at 400,000 units.
"EEDAR expects Nintendo to hold onto its console supremacy in November and December," added Divnich.
EEDAR also expects that the PlayStation 3 will be the only console to show gains in October compared to the prior year, with sales up over 68 per cent to 320,000 units. The Xbox 360 could be down by just under 25 per cent with 280,000 units sold.
