In the comments on RockStar Games' article talking about the new DLC, RockStar has said there is no more DLC planned aside from what's already announced.

"The DLC that's listed is all of the content planned for L.A. Noire"

This seems strange considering all they have cut from the game before launch. But who knows? I know this is from Team Bondi, but it would be a shame if that was it.

Probably planned as in; planned before they receive numbers on sales and whether they should do more or not.

Through the magic of Google, here:

@FauxGland The content we announced today is all of the DLC that is planned for L.A. Noire

@Johnathan_Doe Again, what we announced today is all of the DLC that is planned for L.A. Noire

The amount of time and effort it must take them to record new dialogue is probably why that's all the DLC we're getting

I thought they had recorded enough dialog for two whole other desks or something? And if it's a matter of being too expensive to hire Aaron Stanton for more cases or something, they should make more Jack Kelso cases.  
 
Really they should just make more Jack Kelso cases anyway.

Maybe there was a misunderstanding and they only wrote that much dialogue and that many cases?

They already released or are releasing a lot of DLC so when they are done they will talk more about the future of L.A Noire's downloadable cases.

Is anyone else hoping that the Reefer Madness case will use musical numbers from the 2005 Showtime movie? I'd be okay with them going out that way....
 
  

@RecSpec: Probably because getting more dudes into rooms with cameras and having them act out more cases is more expensive than your average DLC is and they want to hold off and see if people actually buy the upcomoing DLC.

Yup. That would be my guess too.
