Whois reveals that the DevilMayCry5.com domain was registered on May 18, 2018. While anyone could register a domain for whatever is available, upon looking up the registrar GMO, it reveals ties to Capcom with a registration for Monster Hunter: World’s site by both GMO and Onamae as well.
Additional domains for DevilMayCry6.com, DevilMayCry8.com, and DevilMayCry9.com have also been registered on the same day. DevilMayCry7.com, however, has been registered by a squatter, so it appears that Capcom grabbed the open ones for now.
In other Capcom news, the Resident Evil 2 domain name was also recently updated, suggesting a possible near-future announcement for the long-anticipated Resident Evil 2 remake. We haven’t heard about the game since August 2015 but perhaps this could also mean a possible E3 2018 showing.
