No one really knows including the devs themselves.

If possible they seem to want to let people continue.... the whole resources spawn in old areas is really an unknown as well.

It really depends if they have placeholders they can use. Like random rock spawns may have a drop pool addition so they may be a new resource as well. IDK just speculating here.

So nothing is set in stone but I wouldn't expect anything. It is an EA game. Rather see them have freedom to develop the game they want to than feel constrained by the customers wishes in this regard. They should do what they feel is best for their vision of the game.

Personally I don't mind starting from scratch, and it really is the best way to evaluate the changes they may make to food systems etc.
