There will be time for popularization for the laymen. It is not now. It's more important that the knowledge be transmitted accurately and completely, than it is to give a reader's digest for the laymen. We'll have to wait until all of the discovered information is processed, and then summarized. Making a summary early on in the discovery is likely to contain errors. It's also better handled by people other than physicists working on the project.

The standard model predicted it and it was found. That's a major win for the standard model, which is the result of many years of theoretical work, as said above - it was able to predict something completely new, something that was never observed before. I'm not deep enough in the field to see what questions could be answered, and we will see, but it's always a good thing to be able to rely on your model of the world.

So - this is not about other questions in the first place, it's about the validity of the standard model. We can continue from there. (A common title for talks etc is "Physics beyond the Standard Model".)
