I would like to see for P3D :

First Pick - MD80 series, remember all the payware versions are made for FSX, except another company tried a version for P3D and leaks memory faster than the Titanic.

Second Pick - DC-9 series, again P3D is not in the running for this series with the other sims.

Third - This one is a stretch but how about an A330 series, that is complete from the get go! :)
