It seems like, these days, the best way to pry first looks at beloved geek franchises from the studios is to have someone grab a shoddy, not-ready-for-prime-time image and post it all over the net. Worked with X-Men: First Class and now it's worked for ThunderCats.
Here's what sounds like the official Warner Brothers PR description of the Cartoon Network show:
The new ThunderCats will appeal to viewers who have loved the characters all their lives as well as young newcomers to the franchise. A sweeping tale combining swords and science and boasting ferocious battles with the highest of stakes, the grand origin story of Prince Lion-O's ascension to the throne—and of those who would thwart his destiny at any cost—takes on epic dimensions in this sharp new telling. As the forces of good and evil battle each other in the quest for the fabled Stones of Power, Lion-O and his champions learn valuable lessons of loyalty, honor and mortality in every episode.
