Block Fort was in Mario Kart DS, and I don't think they have reused retro tracks yet. Their choice was between Big Donut and Double Deck... and I actually thought Double Deck was pretty neat. It may have been a little large for Mario Kart 64's 4-player cap, but it would be perfect for 8 or 12 players.
Oh well, on the plus side, Double Deck is pretty much guaranteed to be in Mario Kart Wii U.
I believe that the 2 characters they haven't revealed yet will be Dry Bones and Waluigi.The website says that the two unrevealed characters are newcomers to the series, so they are not Dry Bones and Waluigi.
I can't wait until a Magikoopa/Kamek gets a role in MK. Thought for years he was a secret character in MK64.I'm pretty sure that he was in an early version of the game, so you probably saw a screen shot of that.
there is gonna be 20 characters, so the 2 new ones and waluigi and dry bonesI believe that the 2 characters they haven't revealed yet will be Dry Bones and Waluigi.The website says that the two unrevealed characters are newcomers to the series, so they are not Dry Bones and Waluigi.I can't wait until a Magikoopa/Kamek gets a role in MK.

So the game has 8 cups? That's pretty sweet.
You know I'd love for Mario Kart to copy Mario in terms of Worlds and have you go through an adventure mode. So you pick your player and go through Worlds, unlocking special additions to your kart and special items. At the end of each World you'd face off against a Boss. So if it's Metroid World, you'd face off against Samus.
I think that'd be really fun and open up the Mario Kart from simple Cup racer to Adventure racer like Diddy Kong Racing.
