Sort of strange though, doncha think? Why should PSP sales have "caught up" to DS sales? (In reality, DS sales have fallen.)
The major factor is probably saturation of the DS market at the current pricepoint and with the current software.
Nintendo should do something to address this. I'm sure they are prepared for price cuts and have been working redesign prototypes. Obviously DQ9 later this year will give them a huge boost like they haven't had since 2006.
Yes, DS is crushing PSP by wider and wider margins in other markets, but the same people who ranted about how "what happens in Japan echoes in the other markets" can't just ignore that DS and PSP have been a fairly close race in Japan for a good number of weeks, at least compared to the LTD sales ratio.
Edit: though of course, DS software beat PSP software 4:1.
"[Our former customers] are unable to find software which they WANT to play."
"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
Satoru Iwata, Nintendo President. Only slightly paraphrased.
