Just wondering if thats a sign we will get it in HD or if it's always been in SD for HD-Absolute?

There was been lots of talk about this. (other forums as well as avsforum)
People are seeing CMT-SD and Comedy Central-SD in their HD-Only packages.

I can only assume good things. Means it's closing-in time for Comedy Central-HD?

It just showed up (in sd). It's probably a free preview, and won't be around long.
