New Super Mario Bros. could end up being the holiday season's biggest title.

Early sales data indicated a critical hit for Nintendo with New Super Mario Bros. Wii. Now, thanks to Famitsu.com and Enterbrain, we know this to be the case.

As reported today at Famitsu.com, Enterbrain sales data puts first week sales for New Super Mario Bros. Wii at 936,734 units. Enterbrain's tracking period for last week ended on Sunday, meaning four days of coverage for the newly released game.

This sales total easily beats the Wii's previous first week sales record holder. Smash Bros. Brawl, released in January 2008, sold 816,000 in its first week.

While Famitsu.com does not state this, it's also possible that Wii's New Super Mario Bros. may have beaten the total for the DS New Super Mario Bros. First week sales data from alternative tracking firm Media Create gave the DS title just shy of 900,000 in its first week.
