Im kind of scared at and the same time excited that, yes truely, a sequal to the legendary 'Dark Crystal' is on the way. I have never spotted this on sites such as /. etc i simply stumbled upon this thanks to the joy that is wikipedia

Apparently we will see classic muppets on cgi backgrounds (100% cgi would be horrible) and all voices bar one will be the originals! Production is apparently commencing summer 2006, which translated into Australian would be now and release is aimed for Spring 2008 (Australian: Autumn 2008)
