Sonic Riders sequel

I found the info in some pages, hereare the links:

http://www.cubed3.com/news/8314/1/Sonic_Rides_onto_Wii(English)

http://www.hardgame2.com/index.php?zone=news&mod=noticia&id=34124(Spanish)

http://www.sonicstadium.org/sonicnews/317/(English)

also on The Wiicast Episode 54 (http://www.gametrailers.com/player/23529.html)

On some of the pages this game is called Sonic Riders: Zero Gravity

I've never played Sonic Riders before, but I didn't see the point in it though.
If Sonic and friends can run so fast, why are they using hoverboards?

Just another lame spin-off game, really...
