Wondering who’s developing The Legend of Zelda: Four Swords Anniversary Edition? It actually isn’t an internal team.

The studio behind the project is Grezzo (according to the OFLC), who co-developed Ocarina of Time 3D. It looks like Nintendo has a considerable amount of faith that they can handle the franchise!

This seems to be a new trailer for Skyward Sword that has been released separately from Nintendo’s conference overnight…

New racers

Lakitu (kart looks like the cloud he uses)
Metal Mario (shiny, silver kart)

New modes

Race in first-person using the gyroscope
Tricks system like Mario Kart Wii

New power-up

Fire flower (thrown to the front and rear of a kart)
Opponents will spin if hit by the fire flower

Online

Up to 8 players
Local multiplayer as well
StreetPass support – Trade ghost data directly with friends; register others through StreetPass passively so you can play them online later
SpotPass support – Receive ghost data from others around the world

General

Another confirmation of more in-depth kart customization
Courses will break from convention (ex: Wuhu Island is just one lap, as it is a long course with numerous obstacles)
