Based on how long the PMDG`s and the Fenix took it should be clear that there won´t be any new Boeing types (like PMDG 777 or Fenix 737 MAX, or the legendary Jumbo Jet Queen of the Skies and whatnot…) for you to enjoy flying until 2024 - or even mid to end of 2025.
A study-level Airbus A350 might probably never happen.
