I thought Amusement Vision was sold to Take 2 and changed their name to 2k games.
Weren't the main developers of the Sega 2k Sports line-up back in the Dreamcast days?
Nope that was Visual Concepts and a bunch of others. Amusement Vision is in Japan and co-developed F-Zero GX and AX with Nintendo. I think Sega dissolved Amusement Vision with a bunch of other Sega internal developers.
