The latest about HDCP if you believe the rumours is that it won't be enabled on HD movies until 2010. This is due to the high numbers of supposed 'HD ready' TVs that have been sold in the states but don't have HDCP (presumably because they don't have HDMI), or so the story goes. Also Microsoft have just released the HD-DVD drive for the 360 without HDCP which suggests the arrival of HDCP is far from imminent.
Anyway, the original question was a TFT for gaming in which case HDCP is completely irrelevant since it's only for movies and not games. The only reason you are getting HDCP compliant video cards appearing is so they can play HDCP movies from blu-ray/HD-DVD drives (again probably not an issue till 2010).
