So, I ordered my 27 inch iMac about a week ago and today, decided to call my local Apple store and check to see if they had any in stock by chance (I was growing increasingly weary of 'processing land' online). After being transferred by a few people I was told that 100%, there was no 27 incher at the store. I decided I had nothing else to do, so I headed to the store to ask in person. Sure enough, they had EXACTLY what I wanted in stock (3.4Ghz i7, 8GB RAM, 1TB Fusion, 680MX) along with a couple other versions. So now I am typing this out on my new baby in iMac bliss.
TL;DR: Don't believe what the sales people on the phone say, check it out for yourself and you may get lucky!
