Does anybody know on which machines the presentations were running on so far? Even if it'll be August, that's a curiously short time window with no specs released yet whatsoever.
If they haven't released any official statements regarding recommended specs I think your best bet is to use Divinity: Original Sin 2 as a comparison.
Please don't take this as a definitive answer, but for what it's worth it's probably the closest thing we currently have.
