As many as one million PlayStation 4 consoles were sold to consumers across North America in just 24 hours since its release on Friday, Sony has claimed. It is not clear whether that statistic represents a sell-out of all allocated systems across the US and Canada, though retailers have claimed that stock is either tight or depleted. "PS4 was designed with an unwavering commitment to gamers, and we are thrilled that consumer reaction has been so phenomenal," said PlayStation group chief executive Andrew House. "Sales remain very strong in North America, and we expect continued enthusiasm as we launch the PlayStation 4 in Europe and Latin America on November 29," he said. "We are extremely grateful for the passion of PlayStation fans and thank them for their continued support." In August, Sony claimed that global pre-orders for its next-generation system had passed the one million mark. It is believed that the figure was closer to 1.5 million units as the PlayStation business approached the North America launch day. Sony will ship the PS4 across its second major territory, Europe, on November 29. The corporation expects to sell three million units by the end of the calendar year - two months before the system goes on sale in another key territory, Japan. By April, it expects to have sold five million units. On November 22, Microsoft will ship the Xbox One to key countries across Europe and North America, including the UK, Germany, the US and Canada.
