It seems that one of the employees confirmed the previous theory.
One theory of Season 3 Apex Legends said that the map would be changed significantly. Now even a completely new map with two leading themes is mentioned.
What are the motives? By the title you know it’s all about snow and lava.
One of the Respawn employees responsible for animation on his Twitter profile wrote that he was looking forward to Season 3 since the start of the game. The addition of emoji indicates that there is actually something to this snow and lava/fire.
I've been looking forward to SEASON 3 ever since we launched the game. Lots of really cool stuff has been in the works for this one. I'ts so close now! 🔥❄️🔥❄️ pic.twitter.com/bQEfjiVZ9X

The third season starts on October 1, so really soon. That’s when everything will be explained.
