It could be coming next year guys let's all chill out for a second.
We're getting Sinners and Hellraiser this year!!
As for why it's never come till now, it's worth noting that HHN usually does video game properties only when there's a movie tie-in, and the Resident Evil movies were both non-Universal and not especially popular in the States (overseas, they made beaucoup bucks, but over here, most of them made about as much as Blumhouse's Ma). That, coupled with the fact that a Resident Evil maze will be extremely expensive and Hollywood only recently got its budget upped, goes a long way towards explaining why it probably hasn't come.
Put it this way: if Resident Evil came in like 2015, it would've been full of black walls and everyone would've clowned on it.
