All of our scenery for P3dv4 will be available sometime afterwards the release of P3dv5 for free. The current scenery work well on P3dv5 but some minor updates fixes will be required before we can release the installers for our scenery in P3dv5. Also we need to have some applications such as SODE working properly and once that's done we will be releasing our scenery for P3dv5 free of charge.
The airports are: KMIAv5, KFLL, LEMD, SCEL, KBWI, KMSY, KSANv2, KSNA, KRDU, KEYW, TXKFv2, LEBL, MHRO , KRSW and TJSJ.
As we say they will become available with installers and we will announce them in our forums and via Facebook too.
Edit: SODE was released so we should have everything ready by release.
Thanks!
