I believe the "big thing" in 2.2 is really this: (asked after the initial video release of the gamescom "destroyed-cobra-moving-alien-ship")
I can't read it other than: "We can encounter them in 2.2".
i See where you are coming from, but to me hasnt been found is different to havent been encountered in context of speech one to me implies meeting something and one means finding something.
