Sony has sold a lot of consoles since it first started making PlayStations in 1994. The company recently crossed the 500 million mark (525.3 million, to be exact). To celebrate that milestone, Sony is releasing a limited edition PS4 Pro with a translucent dark blue case the likes of which hasn’t shown up on a major console since the fine days of the Nintendo 64. This edition will be limited to a symbolically fitting 50,000 units worldwide.
