I picked Release Day Shipping (Prime) and mine shipped yesterday. My tracking number says it is in my town, "out for delivery." It could be that it did ship and your order page just has not updated yet, because it was *just* shipped. Or you might want to contact Customer Service and ask them. Oh yeah, if you've had it on pre-order for a while, you should be ok, but if you only ordered it late yesterday (Monday) and chose Release Day Shipping, you might have been to late to actually get Release Day Shipping. Either way, good luck! I hope you get the game today!
I would certainly expect Friday was early enough (I have ordered as late as Sunday with release day shipping before). And you are right, Monday night is usually when you get the tracking info. If you don't have the tracking # yet, and it still says not shipping, then you might want to contact customer service and ask them.
I pre ordered it on about August 3rd and it didn't ship or switch to shipping soon yesterday so I just cnceled the order. This isn't the first time that Amazon missed release date shipping for me and it is annoying. I called support yesterday and they said it'll be shipping on time and it didn't of course..... I'm not even calling support again, I'm just not buying this game again.
For those who got it on time, enjoy it extra from me :'( lol
