The wait for new PlayStation 4s and Xbox Ones isn't killing GameStop as it beats earnings estimates

As retail sales slow while gamers go digital and prepare for the next-gen consoles, GameStop is still raking in mountains of cash.

The video game retailer reported $1.38 billion in total worldwide sales for the second quarter of 2013, which ended Aug. 3. While this is down 10.7 percent from $1.55 billion during the same period in 2012.
