I like the look of the series so far (haven't seen the toys), and I'm glad to see the property is coming back. I was a big fan as a kid, and even remember catching the series again on the old "Toonami" block on Cartoon Network around the time when I was in college. I picked up the first DVD set when Amazon had it on a sale for like $20, but haven't had a chance to watch them all yet.
I'm really trying to steer clear of adding any new toy lines to the collection at this point, besides what I already collect, but I'll admit that Thundercats would be tempting. I might be able to avoid it since it will be in the style of the new series, but if there was a MOTU Classics type line of Thundercats, I'd probably be tempted to get a few. We'll see I guess. I do hope the property takes off though, it would be cool to see a resurgence and maybe even a movie.
