Help with buying a motherboard for Ryzen 5600x

Hi everyone first time posting on this forum!

I am thinking of upgrading my pc with the new Ryzen 5600x but I am unsure if I should buy an existing B550/x570 chipset motherboard or should I wait for a new motherboard to be released that will support this beast processor out of the box.
If I understand correctly, every motherboard needs its BIOS updated so it can use this new processor and you cannot update it without a working CPU.

If this is true, would it be better to just wait for a new motherboard to be released or buy an existing one and find a way to update it?

Thanks
