The new map is most likely going to be Valguero, popular modded map from the Steam Workshop. I found a server using Battlemetrics named "test beta" running the map Valguero_P, with known WC employees logging a good bit of time in. I'm only comfortable posting this stuff because Battlemetrics is public stuff accessible by anybody.

Heres some screenshots as proof:

You can also view the Battlemetrics server here: https://www.battlemetrics.com/servers/ark/3486857

There are additional Battlemetrics servers running Valguero that have been used by WC employees. I've seen one used for Filming as well.

What are your thoughts, /r/playark?
