Dead 360

What is technically the fourth Xbox 360 to be in my possession was sent to Texas to be "repaired" last Monday, and was received on Thursday.  I'm very curious how long the "Repair in Progress" period will take because my experience will all prior consoles is that I got someone's refurbished console and not my repaired original.  If this were the general policy then I would assume that they'd simply plug it in, see that it was dead, and grab a box from their mountain of previously repaired units.  I remember a long time ago hoping that I could somehow get an upgrade and receive one of the newer units with HDMI, and while I don't find that likely, I'll still cross my fingers.  Microsoft, you do kinda owe me because the 1 free month of live I get with every xbox repair has hardly compensated the near 4 months of total downtime you've forced due to the horribly overheating hardware.
