Steam has problems with the supply chains and components needed for their new Handheld console/pc Steam Deck. That means the new device from Valve will not release this year, but two months later in February 2022.
Everyone who pre-ordered the Steam Deck got an email:
They say that you will keep your place in the order-line, but shipping dates will shift back for everyone. I checked my order and yeah, it now says “After Q2 2022”. Sad noises.
