I plan to bring that back in. I'm going to rename them to "stories." We enjoy narratives as human beings, and the core Civilization series lacks this. My brother came up with some ideas to make events feel more like a story. I'm going to make the decisions more interesting instead of just a small +1food or something on a tile. I'm also going to make past decisions affect future events. I will show a "story so far" box when new events come up, so we can see the history of our empire.
In addition to the narrative flavor, events give us unique ways to do things. I plan to add an event for Natural Wonders so we can improve them later in the game. I feel choosing how to improve those wonders will be more fun than getting a passive bonus in the tech tree.
One example of an event I think I did well is the scout. A scout's adventures gain popularity with the people back home, and we get the choice of retiring the scout to write tales of their adventures (culture bonus), or send the scout new supplies to continue its rise to fame and glory (upgrade). I like this and want to do more like it.
I can't tell you how happy I am to hear this is coming back. Narrative is definitely something that I feel is missing from Civ, and your previous efforts, and now future plans, will work well in correcting that.
Do you plan on having negative effects events as well? I always thought it would be neat if Krakatoa erupted or something, possibly killing off some population in a nearby city, or adding another tile of land adjacent to it. Certain weather events could be negative too.
