I placed an order for 919 HMP's (not HMB's) in late July and found out two weeks later that my ordered was cancelled because they ran out of clubs. Then i placed an order for the new 921 Forged on Sep 4th in hopes that i'll get them on Sep 17th (release date). I was told just last week they just started building them the week of 17th and are delayed two weeks. Apparently they received some insane amount of custom orders.
Seems like huge demand increase and delays due to covid is causing this... FWIW
