Thundercats LogoAccording to AICN, a new Thundercats show is in the works from WB Animation.

WB animation is remaking the Thundercats as an animated TV series.
The animation style is whimsical, Americanized-anime, along the lines of Teen Titans.
The setting is modern-day Earth, in a major city (possibly LA)
The Thundercats are all teenagers.
Their leader is Snarf (!) who is now a mystic with a “third” eye.
Each of the Thundercats has a weapon with an “Eye of Thunderra” and transformative powers (not just Lion-O)
When they aren’t fighting evil, the Thundercats play together as a rock band. That’s not a typo, or a joke. They are rockin’ cats in their present form.
Mum-Ra now has wings.
And I bet he laughs a bit more than he used to =P
Developing…

I think the best comment from that page was here. I’m not sure they could be more unfaithful to the original material if they wanted. Where are the Four Horsemen when you need them?
