Sega: Mario and Sonic will sell 4 million copies.

Sega has come out and stated that it believes that they will sell 4 million copies of Mario and Sonic at the Olympics, the same amount as the original Sonic from back in 1991. Masanao Maeda, a corporate director at Segas Gaming unit, has said in a report on Bloomberg that the game will get the sales when the game launches, then when the Olympics roll around next year. No Ratio (between DS and Wii) or Time Frame was given for the game to reach the 4 Million mark, but with the Popularity of the Wii and DS, anything is possible. Source: Next-Gen
