The PlayStation 4 hasn’t even been shown off to the public yet, but already the box is on the minds of millions of people across the globe. In fact, in a recent earnings call with investors, GameStop president Tony Bartel said that his company has 900,000 people signed up for its first-to-know list on the PlayStation 4. And he expects demand to far outstrip supply of the console when it launches. Such demand already might surprise some folks. After all, it took a long time for the PlayStation 3 to truly get off the ground and although it’ll likely end this generation with more worldwide sales than the Xbox 360, in the U.S., especially, it’s no match for Microsoft’s console.
