Today CBS announced when its fall shows will premiere, and many of the dates are easy to remember because CBS is essentially launching all of its shows in a single week.  From Monday, September 21 to Sunday, September 27, CBS will premiere all but two of its shows.

Those exceptions include the newest season of Survivor, which premieres one week early to allow a two-hour premiere on Thursday. September 17, and the series premiere of Three Rivers starring Moonlight's Alex O'Loughlin which comes Sunday, October 4, one week late to allow The Amazing Race to have a two-hour premiere.

Continuing in this exciting week of Fall schedules, CBS revealed its lineup today, and while many shows remain fixed, there are some big moves.  The Mentalist, this past season's top new show, will get the coveted post-CSI timeslot Thursdays at 10pm.

And one day after NBC officially cancelled Medium, CBS scooped it up and Patricia Arquette will now see ghosts right after Jennifer Love Hewitt does the same thing on Ghost Whisperer.

From CBS' official press release:

The BAU team tracks a female serial killer who targets powerful business executives on Criminal Minds, Wednesday, February 25.

It's been nine long months since inconsolable Moonlight fans last saw Alex O'Loughlin playing sexy vampire turned private investigator Mick St. John.  Soon, however, he'll be returning to our small screens when he joins the cast of Criminal Minds.

According to Entertainment Weekly's Michael Ausiello, the Moonlight star will be returning to CBS to play a serial killer in at least one episode of Criminal Minds, which is tentatively scheduled to air in April.  This marks O'Loughlin's first TV comeback following the cancellation of his cult-favorite paranormal series.
