I bet it’s a paid add-on like Reno Air Races, but I hope it’s free. Asobo said they were supporting MSFS for 10 years, so it would be really disappointing if they already abandoned it after 3.

edit: So I saw in the FAQ that it’s a standalone sequel, but that most marketplace content should be compatible. Will be interesting to see how they handle the pricing/release, but at this point I’m preparing myself to be disappointed at having to make a pay another 70EUR for it.
