According to the sticky up top, the P3D v4 conversion is complete and released. However, when you check the PMDG website to purchase the 777-300ER expansion, it still shows it is not available for P3D v4. That it is only compatible for v2.4 - v3.x. I imagine this is just an error on the webpage and shopping cart, but I wanted to double check before making a purchase on a wrong version. Thanks.
