Right now, we don't have any news to post about this. Not to mention that, any news about AES for these two sceneries will appear on Cloud9 and Aerosoft websites, not here.
I'm afraid it looks like being more complex than we thought, because KLAX and KDCA weren't really designed in a way that's easy to to add AES support (and, incidentally, it's the main reason why they performed better than EHAM).
And of course, we are now using all the time we have, to continue with KFJK.
