rMBP Issues: Infinite Loop on Initial Setup

Heya folks,

So I received my bright and shiney custom rMBP today. I sit down this evening and go through the initial setup process. I confirm my info, input my master account info, and then click create account....

I get a wheel for awhile, account is being created, then it just returns to the select a language welcome screen. I go through the process again thinking that something glitched and it was no big deal. This time, when I get to the account screen, it makes me choose a different name for my home folder. Weird, but ok. Click create account, spins a bit, then returns to the select a language welcome screen. Do this once more (forces me to choose a third home folder name) before shutting it down and starting over. After start-up it then makes me choose a fourth name...and I give up.

I've set up five different macs (MBPs, airs, minis, and iMacs) over the last couple years and I've never seen any thing like this. I have obviously booked with my Apple Store tomorrow but I was hoping this was an easy fix and not a "they need to order you a new computer fix." Any thoughts?
