Living close to an Apple Store, I gave them a call to see if the keynote is going to be shown on in the theatre area in the back of the store. Apparently, they will be showing it live (9am EDT), presumably from the satellite feed. I then figured I may as well give it a shot and asked if there would be any new hardware on that day. The guy I was talking to said, "If it's gonna be there, it'll be there the next day [Thursday]." That was more than I expected to get, though not quite a confirmation. Unfortunately, it seems that memory is the only configuration variable that you can alter in purchasing from the Apple Store, something to consider when deciding whether to buby online or from an Apple Store near you.
