I went into the Apple store a few weeks ago (July 28) with my Retina MacBook Pro to complain about the burn in, and they ordered me a replacement display. I was hoping for a complete system replacement, as that's all I was seeing people get online, never saw anyone post that they had their display replaced.
They said it'd be in in a few days, and then take about 4 days to fix. I dropped it off last Friday, and the status was updated on August 4th to Step 2, "Repair in Progress".
The status still hasn't changed to Step 3, "Product pickup pending", and it's been a week. Granted, they could have called my home phone and said I could pick it up (I don't know since I'm on vacation), but I would think that they would have also updated the online status page to "Product pickup pending".
I wonder if something's up.... =\
