On the PMDG general forum, Robert Randazzo posted some great information about what we can expect (Mainly with P3D v3). A preview was included of the taxi camera actually being shown embedded into the lower ECAM with the PMDG B773 in P3D v3 and not a pop-out window as previously included. Apparently it only has a slight FPS impact which will make it entirely more flexible on the new, updated platform. Hopefully it wont be too long before its rolled out into an update.
