GameDaily reports that Sony has had a lot of success with the PSP Slim in Japan, with sales of over a million units since its launch in September of this year. That's more units sold than the original PSP did in its several-year-long lifespan. "Titles such as Crisis Core: Final Fantasy VII and Monster Hunter in particular have helped boost Sony's portable in Japan. Sony is maintaining a sales forecast of 10 million units worldwide by the end of its fiscal year next March. The portable sector is still dominated by the Nintendo DS, however. Nintendo is aiming to sell 28 million units of its handheld by the end of its fiscal year."
