Speaking in the final part of Capcom's Resi 7 making of video series, the executive producer Jun Takeuchi reveals that the team at Capcom are already thinking about Resident Evil 8. He says 'Plans for the next title are already in motion, and when you see that game you may find that it is very different from Resident Evil 7 in some ways.'
He also makes reference to 'the next Resident Evil game, and the one after that, every future Resident Evil', so it's clear that at least some people at Capcom see the series as still having a long future ahead of it.
Takeuchi-san goes on to talk about how Resi will evolve as technology advances, but will still retain the core concept of characters up against the odds.
His full remarks are transcribed below:
'As I worked on Resident Evil 7 I wanted it to be seen as a modern masterpiece in survival horror. We want this title to be the start of a new kind of survival horror, and of a new series. We're already thinking about various plans for the next game, but we also want to see how we can continue to evolve survival horror itself. In the next few years technology will continue to advance and what players want may also change but we will always want to create horror experiences where the characters overcome a difficult situation.
That to me is what survival horror is all about, and the next resident evil game, and the one after that, every future Resident Evil, will feature characters getting through crises like this. And so the current masterpiece is jut the beginning, whilst still retaining that core survival horror concept of people overcoming the odds. Resident evil will always retain that essence.'
