Retail sources have confirmed to CVG that PS4 pre-orders must be placed "before next week" in order to guarantee a system on launch date. That effectively gives consumers an August 5 deadline.
Pre-orders can still be placed thereafter, but may not result in a system on the day of release, as demand is expected to significantly outstrip supply. The deadline will be imposed across the UK, and likely Europe, but circumstances may be different across the US and Japan.
However, retail outlets have also been promised additional units for general sale on day one - meaning those who do not pre-order will still have a chance of buying the system on release day.
