During GameStop's latest earnings call, executive vice president Mike Hogan claimed Sony plans to release the PlayStation 4 not only in one region this holiday season, but across the world.
"We know that Sony will introduce the PlayStation 4 globally in 2013, but we are still waiting to see what Microsoft's final plans are," Hogan said (via Seeking Alpha translation). "We have scenarios with one console introduction, as well as with two."
When Sony announced the PS4 in February, it said the platform would be available during holiday 2013, but did not note if that date was for North America or other regions.
The PlayStation 3 did not have a global launch, releasing in North America during November 2006, before coming to Europe in early 2007.
Microsoft is rumored to have its next-generation platform also on store shelves this holiday season. Though the company has yet to reveal its official plans, Microsoft is believed to hold a one-off media event this month to announce the Xbox 720.
