Motherboard makers are apparently eager for the arrival of Intel's not-yet-announced 9th generation Core processor family. Perhaps too eager, depending on how much of secret Intel wants to keep things. Lest there was any lingering doubt about Intel's plans, MSI spilled some of the beans in a news release announcing a round of BIOS of updates for its Z370 motherboards.
Brad Chacos at PCWorld spotted the announcement, which states in no uncertain terms that "the new BIOS updates are fully optimized for Intel 9000 processors." That's all fine and dandy, except that Intel has formally introduced any 9000 series (9th gen) CPUs yet.
