If you were thinking about pre-ordering a PlayStation 4 when it finally hits your part of the world later this year, you should probably get onto that sooner rather than later. An estimated four months out from release, and retailers are already closing the pre-order books, explaining they’ve already sold out of their allocation.
US store GameStop has done so publicly, releasing a statement:
Due to high demand for the system, GameStop is not currently taking additional store reservations for the PlayStation 4.
If you still want one, then either be prepared to shop around a bit and possibly give your money to a non-preferred retailer, or try your luck and add your name to a notification list, to be emailed when orders resume.
