How much? When? Where? Who cares? If you aren't exactly interested in knowing how much the impending Xbox One will cost you -- let alone when it'll actually hit your doorstep -- you can sign up to be notified of your opportunity to pre-order the console right now. To be clear, this isn't a sign-up for a pre-order. It's just a sign-up to be notified of pre-orders officially opening up. So really, what's to lose? Hit the source link below in order to share your email address, and you'll get a $10 Microsoft online store credit for your trouble. (Or, you can hit the Amazon link for those needing an excuse to make better use of their Prime subscription.)
Update: Well, it was nice while it lasted. As spotted by Arlondiluthel, Microsoft's pre-order page now says "we're no longer giving out a $10 store credit, but you can still sign up to be notified of Xbox One availability."
