According to this post there is going to be a 13 part update to the original Cosmos TV show that featured Carl Sagan. And, in my opinion, they picked the perfect host: Neil deGrasse Tyson. Mr Tyson is extremely intelligent, articulate and engaging when speaking about science (or most anything, come to think of it). I am sure they will do a much better job with the CGI than what was possible with the tech available in the early days of blue screens and video.
I thoroughly enjoyed the original when I was growing up and snagged the series when it because available on DVD. My daughter is even a bit of a fan.
The only downside to this is having to wait until 2013 to see the new show.
