Call of Duty: Black Ops 4 Blackout Ambush Plans

A post on Reddit from Treyarch acknowledges that a new limited-time game mode called Ambush is coming to Blackout, the battle royale mode in Call of Duty: Black Ops 4 (thanks Charlie INTEL). Here's the plan:
It’s true, Ambush is coming soon in Blackout as our next limited-time mode in Blackout –- just not quite yet! Down But Not Out will be live for a couple of weeks on each platform, which started on PS4 earlier this week. We’re planning to launch Ambush into the wild immediately afterward, so enjoy the insanity of DBNO while it’s live and let us know what you think of the redeploy system while we put the finishing touches on what’s to come.
