Bright Side of News is reporting that Nvidia has landed a contract with Nintendo to power the company's next-generation DS handheld console. If true, it certainly adds substance to a bold claim made over the summer by Nvidia's CEO, Jen-Hsun Huang, when he declared that Tegra would account for as much as 50% of Nvidia's revenue in the next few years.

All of this is unofficial, but based on the timing BSN speculates that Nintendo would make use of Nvidia's next-gen Tegra chips, which are expected to debut in February 2010. The site reports that the newest DS model is slated for a late 2010 launch, and notes that it may appear at next year's Tokyo Game Show.

In somewhat related news, AMD has reportedly bagged a deal with Microsoft to power its next-generation Xbox console, according to Fudzilla. It is also said that both Microsoft and Sony are planning to keep the current console generation alive until 2012.
