I don't know if this has bee discussed at all, but I just saw this picture in an oldish IGN article and noticed that there is a lot of foreshadowing of events, as far back as 2010, but they are all vague enough you wouldn't know until they happened. Its cool that they had Age of Ultron and all these other events planned out enough to put subtle hints like this into a page.

Theres a lot on here thats obvious like Who is worthy and Schizm but some are vague. Is Steve's vision the reworking of Avengers? And the Whats in the Rings one is unfamiliar to me.

Edit: I see that this is already been posted,
