The new Zelda game for the Wii has been kept under wraps for some time. Not even s screenshot has been released as yet. That could all change next month. According to a rumor, the first trailer will be revealed at an October Conference, most likely to be the Nintendo Business Media Summit which hasn't even been confirmed for this year.
Even if Zelda doesn't appear next month, there's still a high possibility that we'll see the Nintendo legend before the turn of the year.
