Jeph Loeb still saidI think an August 2018 date is at least consistent within the context of the season--there was no indication in the show that the magazine cover was the latest issue. It really just boils down to whether we're taking seriously the out-of-universe assertion that all current Marvel TV shows are taking place before Infinity War, in which case the prop dates can be safely ignored. It seems kind of obvious thatthe next Avengers movie will reset the timeline/universe to some degree so that at the very least Thanos's snap never occurs, so once that happens we won't have to worry about Luke Cage's dates contradicting Infinity War any more than we do the negated Quake-destroys-the-world timelines in Agents of S.H.I.E.L.D. or whatever is happening in future LA in Runaways.
We do have 2-3 more Netflix seasons premiering before Avengers 4 even comes out, all of which probably take place after this season, so assuming Luke Cage S2 occurs in close proximity to/in the same timeline with Infinity War is going to be problematic no matter what.
all the shows take place before the snap.
I'm personally sticking with August 2017.
