TGS: Mario & Sonic will sell 4m, says Sega

Forecast equivalent to almost 20 per cent of publisher's total games sales for last financial year. Sega Sammy's corporate director has told Tokyo Games Show that the firm expects Mario & Sonic At The Olympic Games to sell four million units when it goes on sale later this year.

If the title were to reach the sales figure, it would equal the performance of the first ever Sonic The Hedgehog console title. Sonic's 1991 debut sold four million units, according to the company's website.
