Captain Robert over at PMDG has posted a huge product update on the 777-300ER product, the SP1 release, and some other developments that are currently underway at the PMDG shop.
WAIT!!! There is more!!!!
Finally, Tabs has posted a list of completed 777-300ER Livery list that has already been uploaded to the PMDG Operations Center. This list is a long list, and only contains paints for airlines that actually have the 777-300ER.
Tabs stated that if you are interested in a fictional livery, we will have to wait for someone the FS community to paint it.
