As explained many times already on the forum, when upgrades to existing airports are concerned, we always plan to update everything, but we must start first with products that are in more dire need for updates, because of old technology used or very large changes in the airport.
KLAX is fairly recent and uses the latest tech so, before we'll get to it, there are far more pressing updates scheduled, such as KLAS, LSGG, LSZH and KORD. Which doesn't mean KLAX won't be updated too, but after the ones mentioned here.
