It appears GameStop stopped taking pre-orders for Xbox One because the demand was too high.
This is according to Xbox chief of staff Aaron Greenberg on Twitter, who said demand for the console was "through the roof" at the retailer.
"Demand was through the roof, so pre-orders stopped for now," Greenberg said. "Get on the GameStop first to know list for pre-order updates."
No one knows for sure how well pre-orders for the console, or PS4 are doing as neither company will say - but Ubisoft CEO Yves Guillemot said last week during a call to investors pre-orders were “two times” that of the previous generation.
Xbox One and PS4 are out this holiday season.
