Coming off a strong 2008 season, CBS is taking some bold moves with their new season program schedule. As we wrote earlier, there are four new dramas, a sitcom and a reality show in the mix.

The big news is how it's shifting around some hit shows on Monday and Thursday, while standing pat on Wednesday. Here's what we know right now...after the jump.

Returning: The Big Bang Theory, How I Met Your Mother, Two and a Half Men, CSI: Miami, NCIS, The Mentalist, Criminal Minds, The New Adventures of Old Christine, CSI: New York, CSI, Ghost Whisperer, Numb3rs, 60 Minutes, Cold Case, The Amazing Race, Survivor, Gary Unmarried, Rules of Engagement, 48 Hours

Gone: Without A Trace, The Unit, Worst Week, Eleventh Hour, The Ex-List

New: Accidentally on Purpose, Three Rivers, The Good Wife, NCIS: Los Angeles

Transferring: Medium (from NBC)

Mid-season: Miami Trauma, The Bridge, Undercover Boss, Arranged Marriage, Rules of Engagement, Flashpoint

New comedies:

Accidentally On Purpose is Jenna Elfman's return to sitcom-land. She plays a San Francisco film critic who winds up pregnant after a fling with a younger man. Comedy ensues when she decides to have the baby.

New dramas:

NCIS: Los Angeles is the spin-off from NCIS starring LL Cool J and Chris O'Donnell. Set in Los Angeles, they are part of an elite branch of NCIS called OPS, doing undercover stings and using high tech equipment to catch enemies of the United States. The two-part pilot aired in April as part of NCIS, ending with a cliff-hanger in which O'Donnell's character was shot down in a hail of bullets but survived.

Miami Trauma is the latest from super-producer Jerry Bruckheimer (CSI, The Amazing Race, et. al). It's about trauma surgeons in South Florida, sort of an ER in the sunshine.

Three Rivers in set in Pittsburgh (where the three rivers meet) and stars fan favorite Alex O'Louglin (Moonlight) as part of a medical team that deals solely with organ transplants. The show's creator is Carol Barbee (Jericho, Swingtown, Judging Amy) and film director Curtis Hanson is executive producer.

The Good Wife is Julianna Margulies' return to series TV. The ER Emmy-winner is a lawyer this time out who is forced back to work when her husband is imprisoned.

UPDATE...

Moving The Mentalist to Thursday at 10 p.m.: According to CBS president Les Moonves, "There will be more share available at 10 p.m. for those of us who put on great dramas." That, my friends is a dig at NBC which is devoting all its 10 p.m. prime time hours to Jay Leno. CBS scheduling chief Kelly Kahl added that, "We saw an opportunity to take a strong show and make it a stronger show."

The move also is an attempt to turn Thursday into a superblock, something likely to happen if The Mentalist continues to perform as ably as it has as a 9 p.m. show. CBS anticipates the show breaking into the Top 5 in the Nielsens.

Snagging Medium: CBS saw the chance to add a show to its line up that fitted very well with the shows already airing Friday night. Nina Tassler, entertainment prez, said that Medium would be the child of Ghost Whisper and Numb3rs, if they could reproduce. It'll be interesting if Glenn Gordon Caron gets on better with CBS this go-round than he did when Now & Again struggled on the Tiffany network.

Back to back NCIS: Tassler claimed that putting the two NCIS' together is a smart move because one show will feed into the other, that they share the same type of humor and sensibility. Presumably, CBS knows that based on something more than the two-part pilot.

Also, the Tuesday slot after NCIS is deemed a successful launching pad now because of The Mentalist being there this season and emerging as the rookie sensation of 2008. Interestingly, the Tuesday at 10 p.m. slot, a problem spot for CBS, will be where The Good Wife will try to make its mark. The dual NCIS intro might help the new legal drama, although historically shows have died there, including Smith and Cane.

The Chuck Lorre hour: Putting The Big Bang Theory on after Two and a Half Men makes Monday from 9-10 an all Chuck Lorre block. They tried this once during the season and it drew big numbers. According to Kahl, the thinking is that they're trying to turn a Top 20 show into a Top 10 show. "We feel confident we can blow this show up," said Kahl.

Looking ahead, they're probably also anticipating a time when Two and a Half Men ends its run and The Big Bang Theory could become the Monday anchor at 9 p.m. That's how Two and a Half Men got there, inheriting the spot when Everybody Loves Raymond packed it in.

Dropping The Unit and Without A Trace: Fans have already been commenting how upset they are about these vet shows being cancelled. Tassler said it was a difficult decision for the network and they're sad to see them go.

Midseason moves: Flashpoint will be back, as well as another Canadian production called The Bridge. Rules of Engagement and two new unscripted shows will debut in the second season, too: Arranged Marriage and Undercover Boss.
