Still, in the latter case, the door may be open in the future to nod at other worlds that might be facing the sorts of problems that Westworld is having.
With an over $100 million budget, it’s probably best if HBO doesn’t get too extravagant with the other worlds, anyway.
Therefore, either they do know exactly when it is happening and are being intentionally vague about it, or there are no plans for other worlds to play a prominent part in the series.
Considering the fact that the creative team already sat down and reportedly mapped out the first 5-6 seasons of the new science fiction drama, one would think they would know exactly when and if other worlds would play a part in Westworld.
