Interesting and is validating my theory, that 3DS took the market of the PSP, while nobody took the market of the DS. That's not true completely, some PSP-users got a Vita, some core-Nintendo-fans stayed at 3DS (Pokemon-fans will have been gotten a DS and a 3DS). But mostly 3DS took over the users of PSP while abandoning the casuals that bought DS.
The only difference is, that 3DS is going faster. Sales grew faster, and it is now a year ahead. 14M in PSP's fourth and 3DS' third year. 9M in the year following that for both. I expect 3DS to follow PSPs sales pattern from now on more or less, maybe still being a bit faster in it's lifecycle (and so losing overall a bit more sales).
