Will he or won't he? At press time, David Letterman was still saying he had not decided to move his CBS late-night operations from New York to Los Angeles. Meanwhile, both metropolises have been bending over backward to lure the gap-toothed comic. Here's what each coast has to offer.
*Mayor David Dinkins' office promised Dave a free parking space.
*CBS has offered him three possible New York studios, including the Ed Sullivan Theater.
*City officials drew up the top 10 reasons to stay. Among them: ''Buttafuoco! Buttafuoco! Buttafuoco!''
*His crew wants to stay in New York: ''They live here,'' says Late Night director Hal Gurnee. ''They are settled here. They like it.''
*Letterman's girlfriend, Regina Lasko, works in New York she's a production manager at Saturday Night Live.
*Mayor Tom Bradley offered Dave his office. Really. (But it was a joke.)
*Letterman could move into a 15,400-square-foot Hollywood studio that makes his current digs look like a walk-in closet with seats.
*City officials drew up the top 13 reasons to move. Among them: ''Woody wouldn't.''
*CBS apparently is behind the move too: ''Movie stars are here,'' says one top network exec. ''You have to be where the guests are.''
*Letterman owns a house in Malibu, which he loves.
