Zack Snyder is clearly not finished with the
Army Of The Dead universe. A prequel (more details on that one here) is already on the way alongside an anime spin-off series, and he's also now developing a film sequel.
It's all part of a big new deal that Snyder and producing partner/wife Deborah Snyder have signed with
Dead host Netflix, which will see their The Stone Quarry Productions making all manner of projects for the streaming service. Buried in a
Hollywood Reporter story on the deal is a mention of Snyder working on a
Dead sequel with co-writer Shay Hatten.
