Mario Kart Wii's Battle mode fleshed out

The video above (made by Wii Folder's Josh Thomas) is a spoiler free look at the battle mode of Mario Kart Wii.
I was waiting for his coverage for a while now, and I think it's a bit too late because it's coming out this week, and he got the Japanese copy a while ago.

But it's still a great video anyway so have a look.

(The changed balloon battle is a little disappointing)
