I only did 2-day shipping, but considering it says,
and not,
"PreOrder Now and choose overnight shipping to ensure release-day delivery," I still half-expect it on my doorstep on the 27th. Since they're making promises about delivery right on the page, you'd think they'd tell you which method of shipment you need to choose for them to meet that obligation if it were something special, no?
I guess another way to gauge when you'll get it, as it gets closer to the date, is to see when your card is actually charged, and treat that as the shipping date (don't they only charge you once it's shipped?)
