Not that you need any help buying the game or anything, but you can view Nintendo's Japanese push now.
The F-Zero website has been updating virtually everyday now (the Japanese side, that is) with character and machine profiles, new tracks, AX-GX transfer info, and movies.
With today's update Sega and Nintendo have posted the Japanese commercial for F-Zero GX. There are some flashes of new story mode footage, but other than that, it's about what you'd expect from a commercial about the game.
You can boost over to F-Zero.jp's movie page and download it. Sweet stuff.
