By watching all the time the 737 took to came out, i will say by the time 777 comes out ,they could be thinking already in Microsoft Flight compatibility,,they said the 777 wouldnt take as much as the 737 but the difference in the amount of systems and stuff the 777 have its way too much, and knowing how perfect pmdg add ons needs to be to came out i say it will take a long time, and about the big airbus i doubt it because pmdg and boeing have a good relationship i think the one after the 777 will be the 787 , without counting the small propsLuis Laurencio
