Last week we learned Capcom is working on Umbrella Corps, a team-based shooter set in the world of Resident Evil. Capcom tried something similar to this in 2012 with Resident Evil: Operation Raccoon City, but it was very poorly received and heavily criticized. Operation Raccoon City was a non-canon hypothetical scenario set during the events of the Raccoon City Incident, but Capcom's taking a bolder approach this time. According to producer Masachika Kawata, Umbrella Corps is canon and takes place after the events of Resident Evil 6.
"The game is not a hypothetical, “what-if” side scenario. Umbrella Corps is set in the present day of Resident Evil, which means it’s after the events of Resident Evil 6. It’s almost in an ironic way that we’re using the title Umbrella Corps. If you know your Resident Evil lore, Umbrella no longer exists at this time in the universe; it’s been destroyed. There’s definitely a kind of a background of the Resident Evil universe that forms the basis of the game’s premise." — Masachika Kawata
If you're concerned about a spin-off taking place in the canon Resident Evil universe, producer James Vance later stated that the game (which lacks a single-player campaign) has no "forward-facing story." So while the game is canon, it shouldn't affect the overall timeline much.
