The next generation of Mario Bros games are selling well, NPD figures have revealed, as the New Super Mario Bros game for the Nintendo Wii is reported to have hit the 10 million units sold mark.

This means New Super Mario Bros has already outsold 2-year-old Super Mario Galaxy, suggesting there's a real market for classic platformers, although it's not known whether the sales are boosted by older gamers looking back to gaming glory days, or a new generation getting into some classic gaming action.

Roughly 2 months since New Super Mario Bros was released, the game has sold over 3 million copies in Japan, over 4.5 million in America and around 3 million copies in Europe.
