This is a trailer from way back in the day for an unreleased Kirby Gamecube game. When I saw it, I was totally blown away. It looks like a 4-player Super Star using the Smash Bros. engine. AWESOME. And the music? EPIC (though I originally thought it was orchestrated, it might not be, but it's still tons better than that Zelda medley for SSBB, and since HAL's previous 'cube game, Air Ride, featured orchestrated music, I wouldn't be surprised if this new game did as well).
But yeah, apparently development for this game has moved on to Wii. And it's from HAL, my favorite development studio within Nintendo, so it's gonna be awesome (yes, I actually did like Kirby Air Ride, if not only for the orchestrated Kirby music). Since HAL isn't working on Brawl (which is another reason to be less excited about Brawl), they better be putting all their resources into making and actually releasing this Kirby game! :D
