MSFS showed that these flight sim conventions were not “relevant” to its success back in 2019 when they released the MSFS trailer (not at the event) during the same weekend.
From there, the “trailer” was the biggest news and no one talked about what went on at the boring sim convention (lame presentations including LR).
MSFS does not need the expo, the expo needs MSFS. In fact MSFS could sponsor a convention all by themselves and get more responses from both simmers and developers (booths etc).
I vote for the MSFS Convention 2022!
