The PSP was the top-performing individual console in Japan for the period of 8th to 14th February according to the latest Media Create numbers.
Japanese gamers bought 39,293 PSPs and another 1394 PSPgos according to the stats aggregator, no doubt in part thanks to Namco Bandai's God Eater, which continues to top the software chart ahead of Dragon Quest VI.
However, with the DSi LL shifting 27,586 units, the DSi 18,082 and the DS Lite another 5659 in the same period, the DS family accounts for 51,327 sales, so we doubt Nintendo's losing any sleep.
Meanwhile, the Wii was the second-best selling individual hardware format with 37,501 units, supported by third-placed New Super Mario Bros. Wii in the software chart. PS3 sold 24,811 units, while Xbox 360 managed just 3428 and PS2 1869.
