The earliest customers to pre-order the Steam Deck were set to recieve their units in the matter of a single month, as Valve's take on a portable gaming PC was planned for release this December. However, that is no longer the case, as they've sent out an email to affected customers saying that the Steam Deck's launch is being pushed back by two months. This is supposedly due to material shortages, with Valve claiming that they were unable to get the parts to manufacture units and get them sent out by next month. The Steam Deck is now due to ship out in February 2022.
The launch of Steam Deck will be delayed by two months. We're sorry about this—we did our best to work around the global supply chain issues, but due to material shortages, components aren’t reaching our manufacturing facilities in time for us to meet our initial launch dates.
Based on our updated build estimates, Steam Deck will start shipping February 2022. This will be the new start date of the reservation queue—you will keep your place in line but dates will shift back accordingly. Reservation date estimates will be updated shortly after this announcement.
Again, we're sorry we won’t be able to make our original ship date. We'll continue working to improve reservation dates based on the new timeline, and will keep you updated as we go.
