At this point, it really seems like Resident Evil Requiem director Koshi Nakanishi is just trolling us about Leon Kennedy not being in the game at all.
Despite Leon having been heavily rumored to be in Resident Evil 9 to some degree, he was completely absent from the game's reveal trailer. Instead, the trailer introduces FBI agent Grace Ashcroft, daughter of Resident Evil Outbreak hero Alyssa Ashcroft, who Nakanishi has said is "the new main character."
