If you didn't believe that putting both the words "Mario" and "Sonic" in the title of a video game was a viable enough marketing strategy, you'd be wrong. The DS and Wii versions of Mario & Sonic at the Olympic Games have sold over five million copies combined; we're sure you don't need us to tell you that five million is a lot. Sales will probably only climb much higher when the Beijing Olympics take place later this year.

At the very least, we bet that this ensures a Winter Olympics rendition in two years. We wouldn't mind if that happened, but this blogger's stance is firm -- no biathlon, no sale.
