There are 3 days left in October... how late is "late"?

Been waiting on a custom Vega 64 for over a year now. Already in that time, my Asus R9 390x Strix rog kacked (last May, 2017). That broke my heart.
Since AMD released the RX 580 on April 18th, I thought I'd get a Sapphire RX 580 Nitro+ Limited Edition while I wait for the Vega 64 AIB cards to hit the market. Too late. The mining junkies bought all the OC cards. Limited Edition was sold out! So I quickly scrambled to get the lesser 580 Nitro +.
I almost waited too long. Even they were sold out 2 days later. I got the Sapphire Nitro+ card on May 20, '17.  A week later, most every 8gb AIB cards were gone, too. Less than a month and a half, all 8 gb cards were gone.
If you found one, the price was inflated by $150 - $200 due to demand. Yeah, that was a rattling discovery.
Because I own a new Free Sync monitor, I'm not gonna jump over to Nvidia
and fork out a grand for a card and monitor. That's a big minus to contend with. But I'm not thrilled about the asking prices for Vega 64 reference cards. So every day I've been checking prices and AMD partner roll outs. I'm even watching Gigabyte, too.
