It has four Thunderbolt 3 connectors. Thunderbolt 3 features DisplayPort 1.2
With the old one, you would probably need a mini DP to DP dongle anyway (I did for my displayport KVM on my 2012 Mini), so this isn't really worse, but it might mean you now need a different dongle.
I'm really hoping there's a good/reliable solution for 30" Apple Cinema Display > Dual Link DVI > Mini Display Port > [INSERT PRODUCT HERE] > USB-C
From what I've heard, you'll want a USB-C to DisplayPort+USB-A adapter, and an Active DVI (with dual link) to DisplayPort adapter.
