It depends on the shipping speed. For Sunday releases, one day shipping usually arrives on Tuesday. Because it usually gets there later on the day on Monday, too late for your carrier to deliver it that day. That's the earliest you'd get it. Release day delivery is not available for Sunday releases. If you already have one day shipping, Ordering from Amazon will not get it to you any faster. If you want it on Sunday or Monday, you'd have to get it in a store. That's how it is in the US, but other countries may be different. I got Ocarina of Time 3D on a Monday though. It started shipping on Saturday before the release. That may be the case with Skyward Sword too.
