on the site of KONAMI is no news about it.
there is no real reason to use Strawberry Shortcake.
for mario there was, cause it was for NINTENDO!
people forget the small minigames in it, those were made for the kids who dont want to follow the same patterns all day.
remember, DDR was made to be a game of fun, not game to brag about.
how many could do 8-9 feet songs on their first try?
there is so much nonsense in that article, the probability of truthness is about 0.3684%
so taking this really serious, is foolish.
edit:
i did some more research to provide proof:
http://www.konami.com/gs/newsarticle.php?id=835an artical and a colabaration, but no where mentioned about making a game...
www.newscom.com
ok, the name sounds real, but fake at the same time...
when taking a closer look, nowhere on that site is this artical mentioned..
http://www.majescoentertainment.com/yes they had something to do with strawberry shortcake..
MAJESCO DEBUTS NEW NINTENDO GAME BOY® ADVANCE GAME BASED ON THE UPCOMING STRAWBERRY SHORTCAKE FEATURE FILM, “SWEET DREAMS”
nothing mentioned about DDR..
so basicly, just selective reading, some editing and presto!
we got a new fake newsfact.
