Uh oh.

TV’s new No. 1 network (sorry, CBS) announced its new lineup at yesterday’s upfronts and it’s pitting “Terminator: The Sarah Connor Chronicles” against NBC’s “Chuck.”

That’s bad news for sci-fi/action fans who like both shows and good news for ABC’s “Dancing With The Stars,” which crushes almost everything in its path, and CBS’s “How I Met Your Mother,” which often scores higher ratings than “Terminator” or “Chuck’s” 8 million some-odd viewers. Without a shift in time slot and because the fall run of “Chuck” rarely if ever conflicted with the spring run of “Terminator,” I’m guessing one of those action shows will be canceled by season’s end.

There’s interesting news for “Idol” fans, who have been abandoning the No. 1 show in droves lately. The Wednesday night results show has mercifully been reduced to a half-hour. It’s one thing to keep an audience wondering; it’s another to bore them to tears. Long overdue move there.

As for new fall shows, the network is debuting only two. “Fringe” (pictured right) is a one-hour sci-fi drama by an up-and-comer by the name of J.J. Abrams. Slated to air Tuesdays this fall before “House,” “Fringe” stars former “Mighty Ducks” trilogy/”Dawson’s Creek” star Joshua Jackson as a scientist who investigates paranormal activity with a female FBI agent.

The other fall debut is “Do Not Disturb” (formerly called “The Inn”), a half-hour Wednesday comedy starring recent “Carpoolers” star Jerry O’Connell as the general manager of a hotel and “Reno: 911’s” hilarious Niecy Nash.

Like any J.J. Abrams project (see: “Lost” and “Cloverfield”), “Fringe” has a lot of buzz. And it’s hard to frown upon anything affiliated with an “Arrested Development” alum, who in this case is Jason Bateman; he directed the “Do Not Disturb” pilot.

In the spring, expect more debuts: The Joss Whedon project “Dollhouse,” starring Eliza Dushku, whom I’m convinced is most famous for being hot; the animated “The Cleveland Show,” a “Family Guy” spinoff; and another animated series, “Class Dismissed” (or “Sit Down, Shut Up,” depending on the source) featuring voice-overs by “Arrested Development” stars Bateman and “30 Rock” regular Will Arnett. Also in the mix is “Secret Millionaire,” a reality show version of “The Prince and the Pauper.”

Beyond that, expect a lot of familiar fare (“Idol,” “House” and the 20th[!] season of “The Simpsons”), including a ton of reality programming ranging from the inane (“Are You Smarter Than a Fifth Grader”) to the insane (“The Moment of Truth”). And if someone wants to tell me why “Prison Break” is still on the air, I’d be willing to listen.

Among the shows not to return this fall are two sitcoms with great stars but poor execution: the Parker Posey-Lauren Ambrose vehicle “The Return of Jezebel James” and the Kelsey Grammer-Patricia Heaton-led “Back to You.” Fans of “The Office” might be disappointed AND relieved that the talented Rashida Jones’ awful sitcom, “Unhitched,” was axed.

Also gone, according to the (New York) Daily News: “Anchorwoman,” “Canterbury’s Law,” “K-Ville,” “Nashville,” “New Amsterdam” and “The Next Great American Band.” (The lesson on that last one: There’s only one “American Idol.” You’d think they would have learned that lesson after the frightfest that was “American Juniors.”)

After the break, check out the full Fox fall schedule for 2008. (Thanks to BuddyTV and E! for making this easy for me.)
