Nintendo's Wii games console is showing its first signs of weakness with Japanese sales in March falling below those of rival Sony's PlayStation 3.
According to data released on Monday by tracking company Enterbrain, Sony sold 146,948 PS3s in the five weeks to March 29th, compared to the 99,335 Wiis sold.
If the trend continues and spreads to Europe or the US it would mark a dramatic reversal of fortune for the two Japanese companies. Nintendo's Wii, with its innovative motion sensitive controller, has dominated this generation of videogame hardware since its release in 2006.
The March figures reflect both a slowdown in Japanese sales of the Wii - down by 63 per cent compared to a year ago - as well as a run of stronger sales for the PS3.
