It seems unlikely it could arrive on Thursday. Mine says the same thing as yours, but when I look lower at the history, the only entry was for fedex receiving the shipping info at a 2:24am EST. Since fedex doesn't have the boxes yet and only has the shipping order, it's hard to believe it could get there today.
They won't.
First off, I have seen peoples statuses show the 30th, and also - even If fedex got the packages in the middle of the night, there is no logistical way they could get them to places outside of the Middletown pa area, and eventhen they might not even make the full ground overnight area because it was so late in the night. They also wouldn't have a flight to put them on from Philadelphia, to go to Memphis, and then make it to places further away like TN or OK.
Sounds good all! I am still waiting for my status, I live in Western NY, so I'm not worried. I get overnight stuff fromthere all the time through apple. As well, they have all the way to the 6:30 PM cutoff to physically give Fedex the packages. But we should see updates around 5, as apple must give them the info for the packages prior to 5 pm for guarantee overnight. They may have worked out different info with fedex but that is their normal requirement.
