CW has a pilot for "Nomads". It's about a group of young backpackers who work secret missions for the CIA. If that does well for the network in 2010-2011, I could see them considering Star Trek for 2011-2012.
That's still pretty far afield from space opera. There seems to be a mini-vogue for CIA themed shows this fall (maybe inspired by
Chuck? which would be odd, since that show has only been a modest success). But it's a long leap from there to a show will all the off-putting stuff like spaceships and aliens that networks seem so afraid of.
The CW had a potential space opera pilot called
Plymouth Rock, essentially Teens in Space (yes, yuk yuk yuk) but that hasn't been picked up. If CW was going to delve into space opera, Teens in Space is where I'd expect them to start.
Paramount will expect at least half of the profits they got from
Star Trek XI and would not jeopardize this property from that in 2012 by allowing CBS Television to put out a Trek TV series diluting the brand before Trek XII is released.
It would dilute the brand only if it were poorly done and violated the
Trek XI continuity in some obvious way. I don't see why CBS would bother with a shoddy
Star Trek show in the first place, and the continuity violation would have to be extreme to bother anyone - how many people who saw the movie could really tell you whether it represents a new timeline, new reality, or anything new at all (other than recast characters, which are necessary).
If done reasonably well and coordinated to a basic degree, a TV series and movie series should be able to bolster each other, you know, like they did in the good old days.
