ok so this is how it works.
gamestation has a huge warehouse or main office or sumthin somewhere in the uk they recieve your order then someone goes and finds your game in the main office and send it to you straight from there. they never send it to your highstreet gamestation and get them to send it to you.
to answer your question i would say yes get your hopes up. i pre-order ff13 and paid nxt day delivery and got it a day early so chances r u will see RDD today.
btw if u have ps3 version feel free to add me
