Actually, no. It's more than just "construction worries". SW:GE is a hardhat construction zone. That is a legal status and also a physical status. Construction workers are working six days a week and there is no pavement, only dirt. Furthermore, they can't do "soft opening" because the rides aren't finished. Rise of the Resistance (Alcatraz) lacks its pre-show queue and external shell for the Resistance Shuttle that serves as the entrance to the attraction. And as noted from insiders, the rides are "mostly" finished but need finishing touches.
In addition, there are regulatory milestones to allowing 1) attractions CMs, 2) all CMs, and 3) non-CMs to enter the area and ride the attractions.
In short, we're months away from "soft opening".
