At Konami's E3 2009 press conference, the company showed off the latest Dance Dance Revolution games coming out this year, and the new features involved.
The trailer and demo showed many of the features we've come to expect on the Wii, like Mii support, but it also showed that the game uses the Wii Balance Board.
The Balance Board is shown as an optional feature. The gameplay will be based on shifting your weight on the board, not stepping on and off of it. So more of a hula simulation, or perhaps Fat Joe's signature dance move, the "lean back".
DDR is on the E3 show floor, so we'll make sure to check it out, and report any extra info we find.
