So, yes, I ordered a 15" rMBP yesterday without fully reading up on the prospect of a refresh coming today. Although it's been more than 24 hours since ordering, I still haven't received any email about it being dispatched (although they have taken payment). I don't have the option to cancel the order as the Apple Store is now down. If there is an update to the rMBP line today, is there any chance that I'll get the newer model, or any discount on the older one? Wishful thinking, perhaps. Otherwise, could I take the old model into a store to change it?
