Analyst comments:
April 2015 hardware sales decreased by 4 percent due to the 55 percent decline in sales of [Xbox 360, PlayStation 3, and Wii] hardware, NPD analyst Liam Callahan said in a statement provided to GamesBeat.
[Xbox One, PlayStation 4, and Wii U] hardware sales were stable, and portable hardware increased by 36 percent.
Declines in hardware dollar sales were due to a decrease in average price of 4 percent, due to a drop in console hardware pricing, said Callahan.
For new physical console software, eighth-generation consoles sales grew by 200 percent in revenue, which offset declines from seventh-generation consoles of 62 percent, and portable declines of 32 percent, said Callahan. Overall, console software increased by 20 percent, leading to overall video game software growth of 13 percent.
If the top 10 software list was ranked on a SKU basis rather than a title basis, PS4s Bloodborne, 3DSs Xenoblade Chronicles 3D, and Wii Us Mario Party 10 would make the list.
One possible reason for the soft April accessory sales is the shift in the Easter holiday in 2015. Most of this years Easter sales were likely to occur in March, while sales may have fallen into April last year, making for a poor comparison. (Easter occurred on April 5th in 2015 and on April 20th in 2014).
Gamepad sales increased by 27 percent due to the 83 percent increase in sales from eighth-generation gamepads. The best-selling gamepad SKU in April 2015 was the XBO WIRELESS CONTROLLER, with sales up by 56 percent.
Video game point & subscription cards had the highest sales within the accessories category; sales, however, declined from last April.
