In case anyone is interested, he posted an updated version this morning with a couple of clips to show the differences between the old SD version and the new HD version.
EDIT: Note that the clips contain spoilers from S2.
I really appreciate that he took the time to really detail what happened, how it happened, and how they approached the situation after the initial teaser on HBO. It clears up a lot of the confusion, and the dedication to realizing as much of the original vision as possible in the new aspect ratio is very respectable. I still wish they would release the original version on blu-ray as well though.
Great article. The creator is definitely very passionate.
