I nearly forgot about this video, just ran into it because it was on my favorites. I believe it shows software alone (I suck at Japanese), as it closely follows VGC's own software charts. Check it out:
Now, try and tell me you don't see that handheld shift occurring! The DS literally swallows the whole market! I love the music, too...
Although the vid stops at 2007, while handhelds dipped slightly 2008 (though that was the year PSP saw its own resurgence), handhelds are still consistently selling more software than home consoles, hovering around 60% marketshare.
The biggest handhelds have ever been before the DS caused this shift was when the GBA came out, back in 2001. It only claimed around 1/3 of the software, and hovered around there until its successor came along. Nowadays handhelds are closer to 2/3, though according to the video it got as high as 76.5% in 2006!
