There was concern that a PS4 launch in Europe would come later in 2014, but apparently Sony wants a much smaller gap between regions. GameStop are "still waiting" on Microsoft's plans.
"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,” Michael Hogan told financial analysts.
History is on the side of a staggered release as Sony has traditionally launched new hardware in Japan and North America first, before getting around to Europe a few months down the line. Are GameStop's words via Michael Hogan to be believed? Nothing is set in stone especially as Microsoft is yet to reveal their new toy.
