No one else has commented, so I'll comment.
Shocked at how quickly DS has dropped this year. It isn't like the PSP picked up the slack either. There's a huge depression in sales this year. Monthly Top 10 DS lists on Oricon are pathetic, too. It reminds me of monthly Top PS2 lists back in ~2007. Some really good sales at the top quickly diminishing to nothing at the bottom.
It is also interesting to see that PSP has had a steady climb just looking at the first 9 months of the year each year. Still not "great" on an absolute level, but it's definitely consistently gotten better each year. You can also clearly see the beginning of the end for Wii after 2008. Lack of support is a killer.
