If you want to get an Xbox Series X or S at launch, you’ll likely need to act fast. Last week, PS5 pre-orders opened up in a confusing free-for-all after Sony’s big event, during which I somehow implausibly wound up reserving a console. Tomorrow, it’s Microsoft’s turn, and the company is giving us a little more advance warning about when we’ll need to show up in order to try and grab one of these things. Here’s what you’ll need to know to shoot your shot on the whole thing.

Pre-orders open up at different times depending on your region. Pre-orders open up on September 22, 2020. Here’s all the relevant info from Microsoft’s Xbox Wire:

“– United States (8AM PT): Microsoft Store, Amazon, Best Buy, GameStop, Walmart, Target, Sam’s Club, Newegg, and other participating retailers

– Canada (8AM PT): Microsoft Store, Amazon, Walmart, Best Buy, EB Games, The Source, and other participating retailers

– UK (8AM BST): Microsoft Store, GAME, Amazon, Dixons, Currys PC World, Argos, John Lewis, Smyths Toys, VERY, AO, Tesco, Simply Game, Shopto and other participating retailers

– Australia (8AM AEST): Microsoft Store, JB Hifi, EB Games, Telstra, Harvey Norman, and other participating retailers

– New Zealand (8AM NZST): Microsoft Store, JB HiFi, EB Games, Spark, and other participating retailers

Across Europe, the Middle East, and Africa, you can pre-order online starting at 9AM CEST at Microsoft Store, Amazon, MediaMarkt, GameStop, FNAC, Elkjøp/Elgiganten, and other participating retailers.”

So, United States customers are going to want to be at their computers, ready to roll at 8:00 AM Pacific Time, or 11:00 AM Eastern. Choice of retailer is up to you, but I will say that Amazon already sent out a warning that it might not ship PS5s on time, and so I’d be more wary about ordering from there than from other places.

I am definitely expecting these things to sell out in mere seconds, just like the PS5. That’s just usually the way of new console launches, and there’s a lot of pent up demand for both of these systems. If one is going to be less popular, I’d guess the Series S, but that’s just because early sales tend to skew towards enthusiasts who are going to want the more powerful machine.

Ironically, it’s possible that the advance warning will cause these to sell out faster than the PS5, just because it will allow people to either come prepared as humans or set up bots. The chaos surrounding the PS5 pre-orders was stressful, but catching people off-guard probably bought us some valuable minutes with which to order consoles.
