I actually agree, it really should be displayed on the jam page (and not only for this specific one, but for all Epic Jams in the future).
Also, irrelevant, but I feel the time between the jam and the announcement a bit too long. Of course evaluation and a bunch of things need to be taken care of, but we’re talking about more than 5 weeks (which is almost the mid-time between 2 jams), after this time the rush of the jam is totally forgotten, I rather feel getting ready for the next one instead of talking about the previous one.
