I previously heard that Asus and Iwill had discontinued their AMD duallies, making MSI the last one (not counting Tyan, because they aren't overclocker-friendly).
It is certainly disheartening if the MSI has really been discontinued. If it has, it would be a good idea to hurry up and get one. It is the best dual AMD board for overclocking, anyway, and soon it will be a commodity item.
