I can confirm the initial discovery happens in 2058 and then moves ahead in time. Don't know what happens for sure, like if the plots that had that date are 100% correct or not. From going over them I can almost guarantee people have pieces of the puzzle and are trying to fill in the rest like I am. I didn't try to write a full synopsis though because it seems obvious not one of the leaks has the full story.
I can confirm a couple more things too. Only a couple, so I have no real clue about the whole plot. But we already knew Weyland was involved from the logo. It just doesn't seem like there's been one with that date that screams completely true yet. At least by the time you make it to the end. Some of them start ok, and are similar, but most likely no one has the ending right. Some are just way too short for a three hour movie, even if they've left parts out.
