PS4 pre-orders must be placed “before next week” for launch day delivery
[Update: Sony say it's looking at a "sell out situation with PS4 pre-orders"]
Sources are reporting a PS4 pre-order deadline is being set in place. Pre-orders must be placed before Monday the 5th of August to guarantee delivery on launch day.
PS4 pre-order deadline to guarantee launch day delivery
The move is apparently due to the excessive demand. You can still pre-order but you’ll run the risk of not getting a console on day one. Apparently the deadline is next Monday, the 5th of August.
Ironically at this point you might be better off waiting as Sony will make additional units available to the shops on launch day. If you miss the pre-order deadline then you stand a better chance of queuing up to get a unit first.
