Ofcourse, there are also advantages to this approach. Firstly that it allows for surprises. Secondly that it's realistic; you don't always know what to expect. And thirdly, I suspect the Event Team does it this way so they have more flexibility to adapt to the players' choices. (Like whether an event will be talking or fighting depending on what the players decide. If they announce in advance the event will be fighting, that flexibility is gone.)
My own opinion on this is that, personally, I like the surprise with the current approach, but what I see around me is that most players would prefer that a little more details on what the event will be are announced in advance, so that's probably better.
