Check this out:
YouTube - Thundercats - Coming to Cartoon Network!

This is totally different then the one I saw as a kid, but in all I think I might watch it what about you?

It's definately very different from the first one but it's definately got my interest. To me it looks like it's going to be an interesting take on the series most likely not simply redoing the old series but doing a lot of new things completely while keeping the spirit of it. Or at least that's what I hope it'll be. Fingers crossed.

I'm scared.

I liked the original show as a kid. I hope the new one is good too -- I will definitely be checking it out at some point.
If it's not I will be really disappointed.

It looks like it could be interesting. I will definitely have to try watching it when it comes out.
But it will be weird watching it since I grew up watching the original Thundercats.

And watching that makes me think of the Escaflowne movie. :/
