PMDG are just people who have dedicated a large amount of time in refining their craft, marketing, sales strategy, etc... It's kinda funny how some treat them as if they are supernatural and untouchable. Credit where it's due, they have worked extremely hard in producing some excellent models. To answer your question, it's not a question of "IF" we will ever see the x plane equivalent of PMDG...but "WHEN". TBH with you, I think IXEG will be it. And head to head, so far, the IXEG 737 exceeds the PMDG 737. But let's wait and see what the final results will bring.
