According to a couple of ECC reports found via @momomo_us, Gigabyte could be working on several Z690 motherboards including an updated version of the Tachyon and Aorus Elite. A number of other boards listed include the Gaming X, UD (Ultra Durable), Aorus Master, and Aorus Extreme.

ECC filings are never 100% accurate so take these results with a grain of salt. However, nearly all the board names Gigabyte published have already been used in previous motherboards. So there’s a good chance that Gigabyte will reuse most of the names if not all of them.
