Earlier this year there was a lot of news about a large number of X570S motherboards coming out. To date, I've only seen 4 available in the US on Newegg/Amazon, which are two Gigabyte, one MSI and one Asus. Anyone know why so few got released? I went to Gigabyte's website and it shows a bunch of other X570S motherboards on there that don't seem to exist (unless they are only available in other countries).
