Nintendo is planning on releasing an add-on to play movies and .mp3's, I believe.

I think it's just safe to say that the PSP is the first ever legitimate contender to Nintendo's monopoly on the handheld market, which is really my main point in displaying those numbers.

It was unfortunate Nintendo decided to create conflict within the company by trying to manage two haldheld systems simultaneously, because they voluntarily weakened their own stranglehold on the market, which will only make it that much easier for Sony to be considered tough competition.
