GameRevolution: "First, it was confirmed that the PS4 outsold the Xbox One during the month of March. This marks the fifth month in a row that PS4 has led the Xbox One in sales within the territory. The last victory for Microsoft was last October, which was attributed to both strong first-party software as well as the recent release of the Xbox One S.
However, the top-selling gaming brand was Nintendo with its newly released Switch. The console is confirmed to have sold more than 500,000 units in North America alone during its first week on the market, and had more to show for it in subsequent weeks with speculated total sales during the month being around one million. Demand has outpaced both expectation and supply at a level that surpasses the record-selling Wii during the same length of time post-launch."
