Just a thought but, presumably (if elements of the prequels are indeed being retconned here, and the two films are not actually being knocked straight out of the continuity), I'd imagine this will likely have to be set in the latter portion of the 2090s, since the company is still Weyland Industries earlier in the decade in Prometheus and Weyland-Yutani doesn't come about until at least a few years later, before the launch of the Covenant prior to Alien: Covenant's start, and Hawley keeps explicitly referring to the company as Weyland-Yutani when talking about it in regards to this show. I wonder if maybe we might actually be seeing the merger happen here in the show, or if Weyland-Yutani will already be established from the get go?
Of course, if Prometheus and Covenant are full on getting dropped from the continuity on the whole, then none of these details would be relevant and Weyland-Yutani could have existed for decades prior to the start of this show if they really wanted to go that route.
