The PSPgo is now on sale in Japan and first day sales were impressive with the company moving 28,000 units.  That number is compared to PSP-3000 sales of 140,000 unites in October over a 4 day period. Only time will tell if the PSPgo can surpass that level.

The release was also supported by download titles which included Persona 3 Portable and Dissidia Final Fantasy Universal Tuing, alongside download-only titles that included Disgaea Infinite and LocoRoco Midnight Carnival.

The Nintendo DSi however is still king in Japan, having sold 170,000 units in the first two days of sale. [GamesIndustry]
