Well, thanks for the additional info, Paul!
Actually, that's pretty much what I predicted, 4 tracks, plus their reverse version.
What I didn't see coming was the new game modes - ace idea!
the concept ship models look absolutely frickin fantastic as well! The only thing that slightly bothers me, if there are 13 new models, that certainly means 12 concept models for the existing teams, plus one special ship for the fancy new game mode. Which leaves one question:
Where in the world are Tigron and VanÜber? (not that I'm complaining, but I was definitely expecting to see them again...)

@zeeZ: Divine Excrement - I am laughing my guts out! Brilliant! Would give you some more rep if the system let me...

EDIT: The new Goteki model is so unbelieveably sweet, I might just have to switch teams. Have been dreaming about Goteki sometimes anyway, especially when I fail to accelerate my heavy Aursome at the start of the race
