Battlefield V battle royale in March 2019
According to the just released Battlefield V roadmap, the battle royale mode for the game won't be released until at least March 2019. Talk about just handing the "W" to Treyarch and Activision with their Blackout mode in Call of Duty: Black Ops 4. By the time March rolls around, Blackout will have had a solid five months to be refined and handle customer feedback.
Battle Royale comes to Battlefield with Firestorm and the war reaches Greece as the third Tides of War chapter is unleashed in the Spring.

Firestorm:Greece map: Join a massive aerial invasion along the Cretan coast. The Allied side is desperate to cling to the island under attack by the Axis, attempting to break through the British defenses air superiority and paratroops. This map brings all-out war defined by a power struggle between tank control versus air superiority.

Again, just like the other chapters, Trial by Fire will let you tackle weekly events to earn rewards, and as you progress through the chapter, further unlocks await.

As mentioned, the roadmap of content releases for Battlefield V was revealed today. Though their battle royale mode, Trial By Fire, won't be out until March, there will still be plenty of additional content that should tide you over until then.
