PGC is now hosting some footage of the upcoming Mario Kart game that someone managed to capture from a CNN broadcast yesterday. The DIVX file is 15 megs and you can head over here to grab it directly. If you want to download a smaller version of it or get the full broadcast that also included some F-Zero stuff head over to this page!
Beware the dreaded Planet Gamecube pop-up ads! If you're feeling like a cowboy you can right click this link and try to download the entire video from n-finity.com. They also have some supposed scans of a new Super Mario RPG at the site.
