It does seem super surprising for a game to have literally zero promotion less than 2 weeks before the launch.
Maybe - they are going to release it, gauge the reviews, look at areas that need to be improved, and then push out an update to have a more polished product. Then push out some marketing or make more announcements around it?
Seems super weird to put so much effort into a game and release a new one with new licenses and not even promote it? Unless the approach is like a Beyonce album and just drop it all suddenly hoping the crowd goes wild
