I know, but why? What would have come of it? I recall it being one of Nintendo's big, fancy new games for the Wii... people were talking about putting the guy in BRAWL... but they, poof, it died.
Maybe they'd overestimated the Wiimote's motion capabilities when they proposed it. Maybe the 'HAMMER' was meant to be a weapon in which the player swings a big hammer.
Of course, they could technically do it now if that was the case, with Wii MotionPlus and all.
