This would depend on what kind of PSP it is and how expensive a DSi costs where you live. a PSP MIGHT cost 200$ when a DSi could cost 250$. this would mean the company you ''traded'' with, would loose value since the PSP you traded for a DSi has 50$ value more then your PSP.
the dsi rocks the psp is not as good the dsi!:) the right answer

DSI

No, you can't swap a DS for a DSi but you can trade in your DS and get £75 off a DSi.
The DSi was launched in 2008, the PSP at the end of 2004.
