Update: This looks very suspect, frankly. The game was never even officially announced. So this story is, “Game that was never announced has been canned according to US retailer.” And for that we truly apologise.
According to this TripleTags story, Beatiful Katamari has been canned for Wii.
The news comes from an email just sent out by Wal-Mart to US customers.
A Wii version isn’t even listed on GamesPress, so if you were holding out for this in Europe, well, we don’t really know what to say. Nothing, probably.
