“Steam Controller ran out faster than we anticipated, and we hate that not everyone who wanted one was able to get it. We’re working on getting more in stock and will have an update on expected timeline soon.”


Looks to me more an endorsement of preordering when stock is limited. If delivering laptops in the order it received took 6 months then a first come first serve would have meant no laptop at all within 6 months for many people who wanted one.
It’d come down more to who is the luckiest and has the best bots.
