Since the launch of the original PlayStation in 1995, it, and its successors have been popular worldwide. To this day, the PlayStation 2 sold over 155 million units, and has the highest sales number compared to any game console ever. With the PlayStation 4 on track to eclipse the total amount of sales that the PlayStation 3 made through its lifetime, it was hardly a surprise when Sony revealed that over 500 million PlayStation branded systems have been sold. To celebrate this achievement, Sony will be releasing a very limited edition PS4 Pro console. Only 50,000 of these consoles will be created, and they'll be selling for $499.99. The special console comes in a dark blue color, with a translucent see-through casing, a PlayStation Camera, a headset, and a special controller. You can also opt to buy the controller alone for $64.99. Both will go on sale for a short amount of time on August 24th.
