According to Nikkei Keizai Shimbun, the PSP has hit quite the landmark in Japan. By the end of February, Sony has hit 5 million domestic shipments of the portable. While the PSP is always in the shadow of the DS as far as press and sales are concerned, many seem to miss the fact that despite trailing the DS in sales, the PSP is a bigger seller in Japan than most other consoles.
The business news reporter also went on to say that software development is being increased and the PSP is in a growth period. As Sony reminds gamers, the system adoption rate is "the same as that of the original PlayStation, which shipped one hundred million units."
I look forward to the announcements on the new PSP games being created in Japan.
