Well I'm just hunting around for dates right now, Futureshop has a release date in stores of the 10th up here in Canada, with a pre-order of the 8th.
So you can bet Walmart up here will have it on the 8th as well, along with EB.
However, the FS webstore has a list price of $39.99 with free shipping.
Check it right Here if you want.
