What you are about to read should be taken with a grain of salt but the sources for this rumor are very trustworthy, so we can expect an official confirmation at any point.
Anyway, GameReactor have reported that UbiSoft is planning a Far Cry 6 reveal during their dedicated live stream on July 12. We don't have any other information at the moment, but as I said, the source is trustworthy, so there could be something in this leak indeed.
It's been a few years since we had a proper Far Cry game so let's keep the fingers crossed and hope for the best.
