Yes, let us wait and see. What I like in it is that it has a bit closer ties to actual world as is, and that it gives great flexibility. If we have something happening in real world location, we already know how it is, it is just a bit more decayed, probably plagued by constant blackouts and lack of fossilic fuels. In parts where there is no food, also quite likely lack of people. It would be far more convenient to write in that way, as everyone can quite easily imagine it and have real life references.
