In the "making of" video series for Resident Evil 7, executive producer Jun Takeuchi states that the team at Capcom are already brainstorming Resident Evil 8. He says that "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 refers to 'the next Resident Evil game, and the one after that (etc.)" clearly excited about the future of the series. Takeuchi continues, talking about how Resident Evil will evolve as technology advances, keeping at the bleeding edge so to speak. He ensures that the core concept will remain the same, however.
"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."
