Microsoft released its Xbox Series X and Xbox Series S consoles on November 10, and as you probably already know, they've been super-hard to get. Pre-orders came and went quickly, and while the new consoles do show up at online retailers occasionally, you have to jump on them quickly before they're sold out again.
On Microsoft's own website, the Xbox Series S is currently in stock, but there's also some bad news. The company has added a note to the listing to say that the new gaming console won't ship until the end of December. The Xbox Series X listing just points to other retailers, which are all sold out.
It would seem that Microsoft is just going a different route than other retailers, simply pushing back shipping time based on availability. What other retailers are doing, and what Microsoft usually does, is simply say that something is sold out until there are more available.
But the bad news is that if you want the next-gen console, you might not get it in time for the holidays if you order from Microsoft. As always, if you're trying to get your hands on these hot items, you're best off keeping an eye on all retailers.
