No, you are not seeing things: The 1080p is SMALLER than the 720p this week. Amazon just... did not release the episode today, so we had to use a different source. This may also have resulted in a slight quality loss for the 1080p, but it's minor enough that the 720p should be unaffected. We do intend to re-release this one with Amazon footage once that actually becomes available.
