The 707 is yet to be released of course, but unless Microsoft are planning to publish another aircraft before MSFS2024 releases (which seems unlikely), it's needed to bring us to the 30 aircraft they're promising for this edition.
I already own the ATR & An-225 separately, not really sure if I care enough about the others to justify the price premium myself. Most likely going to get Premium Deluxe, as there's several aircraft there I'm much more interested in.
