To confirm this is the company NPD, which publishes monthly sales data of hardware and software for the United States.
Sales have increased from 3,000 units sold in April to 56,000 units sold in May.
As a possible cause of the increase in sales seems to be the bundled with Borderlands 2, which was released last May the 13th. On the home console market, the PS4 still continues to rule though. Which confirms the best selling home console for the fifth consecutive month!!
As always thanks for reading and make sure to check back soon!
