Gearbox is said to love both Sonic Team's Dreamcast original and sequel, which utilized a set of special height and motion-sensitive maracas and required players to shake the maracas at varying heights in beat with the music, so it's not too far-fetched of a proposition--especially since the company is working with Sega on the upcoming Aliens FPS.
Given the popularity of the Wii and the capabilities of its controller, a Wii edition of the always-popular-in-a-social-setting Samba could tackle two of the biggest barriers that prevented the original from taking off: the sinking popularity of the Dreamcast and the cost of the $80 maracas, which were not bundled with the game.
Shacknews attempted to confirm this news with both Sega and Gearbox, but had yet to receive a comment as of publication. In the meantime, this writer will be fishing out his Dreamcast and imported copy of Samba de Amigo Ver. 2000 and shaking two fistfuls of awesome to such hits as Bellini's "Samba de Janeiro," Reel Big Fish's cover of A-ha's "Take on Me," and Hideki Naganuma's Jet
Set Grind Radio anthem "Let Mom Sleep."
Why does that vaguely remind me of the Johnny Chimpo from Super Troopers...
