Man, alot hype but Hornady wasn't ready to deploy them to the public. Heck of a marketing strategy, shame on them.
This is so common across all companies. The timing to launch/develop/manufacture new products right now is a nightmare with lingering component shortage and a tight labor market. I live it everyday as a manufacturing project leader.
Industries are generally beholden to some launch windows whether real or imaginary dictated by customers or trade show schedules.
You either announce things early and miss your schedule or you don’t announce something until inventory is made. Those are the 2 options and the management generally picks based on whether they came from product line/market or from manufacturing/engineering.
