KLAX was released in 2011, at the same time as the latest version of KORD V1.
KORD V2 for P3D, which was a complete remake in PBR, took about 2 YEARS of work, and if MSFS didn't came out, we would have lost money on it.
But since there's a perfectly fine KLAX available for MSFS, we don't have any plans right not to remake KLAX. Maybe, in a few years time, with new simulators and new graphic engines, but surely not for the current P3D versions.
