Just got my disc via fed ex. Not a retail copy, not even close. I'll update with a pic in a few. It's just a clear green case with not retail copy beta, blah, blah on the disc itself. I'll try it and see if it's even a full version in a minute.
Edit: On second thought, don't want to break the NDA, so just know that it's not the retail version. Just a green case, no label and a disc that barely looks professional.
