It's hard to say whether Trios will come back again in Fortnite. The decision from Epic Games won't have an immediate reversal, and we don't have a clear idea of what the team has planned for the game's future chapters.

It could return as a limited-time mode like in its heyday, but as noted above, many fans used Trios as a permanent way to connect with friends and play matches. It would be a disservice to this audience of players to slap it on and lose it again, but time will tell if we'll ever see it in the future.
