Perhaps Biostar was a bit envious after the MSI tease, so here is their "Racing X570GT8". This is the first actual real photo of X570, the new chipset for ZEN2 / Ryzen 3000. 

Looking at the motherboard you can see a powerful VRM, likely to deal with the rumored 16-core proc. The board draws juice from 8+4 pin EPS connectors and the leaked PDF reveals a 12-phase VRM. The usual suspects are there, two metal-reinforced PCI-Express x16 slots and yeah, that would be PCI-Express gen 4.0. Memory support is listed up-to 4000 MHz btw, there are three PCIe x16 slots and one PCIe x1 slot on board. In terms of connections, we see one gigabit Ethernet port and one DVI display connection. Finally, this data confirms that the X570 chipset supports fourth generation PCI express / PCIe 4.0. We will probably find out more during Computex. An active chipset cooler (fan), I have not seen that in a while. Hope it's not a trend.
