You found my secret hint!
May would be great but treat it as a NET date.
Ship graphics are needed for marketing. If the reveal trailer and the release date are the same day, that'll massively decrease sales for a game like this. Best to have a few months to build interest. Some games even artificially delay release to give them more marketing time.
Bigger games don't have this issue because they can do a cgi/in engine trailer years before the game is ready to be shown.
you realize you have a serious answer to a joke post right?
