Yes, I think so too. By the way, is there any news about a release of South Park: Bigger, Longer and Uncut on Blu-Ray? It still needs a decent SE, and actually using the digital files this time would make it look a lot better than the current dvd.
It should be noted that it's probably matted widescreen, like the Justice League cartoon series. I checked some episodes online and there's an awful lot of headspace in about every shot.
