Ok so they're set into making Prometheus 3, or Alien Covenant 2, or Alien "insert name of the new ship and crew as subtitle here"
I agree with most on here, please don't leave it in development hell for half a decade, wonder if this next entry will be the last in the prequel series, or if there still trying to set Covenant as the start of a new trilogy.
Just realized if they immediately set into production next year the 3rd upcoming Alien Prequel will be out by Alien's 40th anniversary in 2019
