I don't know if this will be the end of Sid Meier's Civilization franchise?
Highly unlikely. Civilization is one of the biggest franchises in gaming, arguably the biggest in 4X strategy. It is iconic. Not to mention that it is practically synonymous with Firaxis. It is their bread and butter. They are not going to give it up making civ even if civ7 does poorly.
IMO, these layouts just show that Firaxis is perhaps scaling back their ambitions for civ7. It is possible that they don't need as many artists for the DLCs and expansions as they did for the launch of the base game. Or maybe a lot of the artwork and graphics for the DLCs and expansions are already done so they don't need their work anymore. But that does not mean that civ franchise is dead.
