We already knew the show was going to start filming soon, but this is the fist we've seen of a plot summary and something more official on Netflix channels (Even though it has now been pulled). I wonder if the plan is to announce this officially along with other RE content such as Resident Evil 3 previews.
The show itself sounds like it's indeed going for something more akin to horror than the films that will explore the background of umbrella (Which had been rumored as well).
