Resident Evil 5 is a big hit. Know what Capcom likes better than big hits? Making big hits into big hit sequels.
According to RE5 producer Masachika Kawata, "We haven't decided whether we're going to make Resident Evil 6 yet... But if we do, it could take anywhere up to eight years, but hopefully only four."
It could take up to eight years, but hopefully only four?! To recap, Resident Evil came out in 1996, Resident Evil 2 in 1998, Resident Evil 3 in 1999, Resident Evil 4 in 2005 and Resident Evil 5 in 2009. And possibly RE6 in 2017?
Expect a gajillion spin-offs and Wii ports in between then.
