Yes, DVB-S2 is the new "standard" for HDTV. Normal HDTV is transmitted in mpeg2, DVB-S2 is transmitted in mpeg4/H.246. Normal DVB-S cards or receivers are unable to demodulate that signal.
Receivers from PACe, HUMAX and PHILIPS are announced but not really available to the public. Also the ReelBox can receive and visualize mpeg4/H.246.
KNC ONE has announced a DVB-S2 card to be released January 2006. Watch this space!
