According to a reputable leaker (or, at least, as reputable as they come), Resident Evil 8, otherwise more commonly known as Resident Evil Village, is just one-third of a new Resident Evil trilogy that started with Resident Evil 7.
While Capcom has not officially confirmed this yet, if it is true, then it means that players will spend at least one more title with Ethan Winters as the lead character.
Resident Evil Village Part of The Latest Resident Evil trilogy
The Resident Evil franchise has never really had a formal trilogy of sorts. However, one could argue that you can split the mainline titles prior to Resident Evil VII into two trilogies.
The original Resident Evil along with Resident Evil 2 and 3 make up the first trilogy. All three games predominantly took part in Raccoon City. Meanwhile, the second trilogy, composed of Resident Evil 4, 5, and 6, takes the series international. The next trilogy, as per AestheticGamer aka Dusk Golem, started with Resident Evil 7 and will end with Resident Evil 9.
Per his exact words, "RE7>RE8>RE9 have a connected, planned out story as all ended up in dev close together."
The leaker explains further that Resident Evil Village will help clarify everything that didn't make sense in Resident Evil 7, which actually sounds logical. So far, Capcom has done a great job in keeping the full story of Resident Evil Village under wraps. This is especially praise-worthy considering that they've spent the past couple of months hyping up the game, going as far as releasing two demos (the second one still has yet to release).
