According to this new article from CVG, Capcom UK's head of marketing thinks that it makes perfect sense for Capcom to explore action "more fully" with Resident Evil.

This is what he said...

"We've seen the popularity of Resident Evil increase massively as the series became more action oriented - Resident Evil 5 is the biggest seller in the series. So, it makes sense for us to follow this action area more fully."

He added of Operation Raccoon City: "The dream would be that the millions of Call of Duty fans that are enjoying these fast-paced online games are attracted to this Resident Evil."
