Sales of the 3DS rose 260 percent after its price reduction in August, Nintendo announced today.
The 3DS, which saw a $80 price reduction in August, sold 185,000 units after the price drop, according to data provided by the NPD. The 3DS monthly total was 245,000. The system now retails at $169.99, having originally debuted at the $249.99 early in the year.
In response to lower than expected sales, Nintendo reduced the price in order to make the system more appealing beyond its technical capabilities.
In other Nintendo news, the Wii sold 190,000 units and the DS 165,000 in the month of August, and the majority of the best selling titles for the month belonged on Nintendo platforms.
I believe the 3DS will be a long-term success as long as Nintendo doesn't go and piss off all of their cutomers by releasing a 3DS redesign next year that obsoletes the current model.
