A little history is in order too: The PurEffect launch was originally planned for 1st Q, 2007 (based on the above link). That launch date was pushed back to 2nd Q, 2007 (per CK-41 website). Now it actually appears that they should be ready for launch 3rd Q, 2007, as they have started filming. Too bad the website has not been updated.
There were reports of issues at CK-41 which caused the delay from 1st Q, 2007 to 3rd Q, 2007.
