Estimated Ryzen 4000 availability

I want to build a pc to enjoy the release of World of Warcraft Shadowlands on Oct 27th. When do you think the 4000 series will be available to buy, roughly?

OK, that's helpful. It was that historical view/trend I was after so it sounds like I should carry on playing wow on my potato and target a November purchase, whether that be the new 4000 or perhaps a slightly cheaper 3600.

Thanks fella's,
