Skyward Sword hasn't been the healthiest game, lately. It's weekly sales have dropped below 10k, and it's nearly dropped off the Top 100. It sold a lot, at first, but it really doesn't seem to have much by way of staying power, for one reason or another.
I'm somewhat optimistic in hoping that this streak continues. I wasn't a fan of the direction of SS, and while it's sales thus far have likely turned a profit, drooping sales in the long term might spur another shift.
Oh well. May the market speak.
