I understand, but that's the point: for the audience it's not so interesting to see the results without the winning entries, so to maximize interest, the jury should wait to present the results until they're ready to publish the winning entries too. It's not as if the IOCCC is working on a tight schedule anyway.

This is like hearing who won in the Olympics and then watching the games later at night; sure, you can do that, but it's much more exciting the other way around.
