Since the first Higurashi season, I knew'd all along that Mion actually harbors feeling for Keiichi, and the first Rei OVA episode clearly exposed at.

Spoiler:

Is there any evidence that she even knew of their existence before her uncle called her? She sounded really surprised when he mentioned them. And even if she did, would she have actually developed a plan that hinged on Keiichi forgetting his own trunks at home?

I don't see how that's a revelation, considering that fact had been blatantly obvious since at least Watanagashi-hen.
