Televised Trek is dead.
Nah, it's only sleeping.
The current corporate attitude seems to be that Paramount overdid it by having two Trek shows on the air and making movies at the same time. (Jonathan Frakes weighed in on it here.) So now CBS(/Paramount) is playing it more cautious. I'm sure there will be a new Trek TV show someday, but probably not until after they feel the Abramsverse films have run their course.
