Do what I did last year, as soon as it's announced call up the store! if they dont have it ask when they will, if they say friday just get it friday but call up again in the morning, double check and reserve it. That's what I did.
Im dying for this refresh, my laptop died and I had to buy a MBP and I was talking to someone in apple the other day and he said as long as it happens within 28 days of me getting this one then I'm fine, but I need to get it by the 4th March! Getting quite worried now that there's no rumors about the 15"
Looks like we're in the same boat then, needing the refresh as soon as possible. Yes I think I will call up the store as soon as they are announced. Man, I am not going to get any work done tomorrow.
