I think Sony has got to be a bit worried a bit, but I'm not sure how much the PSP has played into the equation. I bought a PSP, but I'm still going to get a 360. Had they been released the same week, I would have held off on the PSP and gotten the 360 in its stead.
Sony's marketing team has not even begun on the PS3. It's still a bit early to tell. It definitely has caused some heated words between the two companies. Each will have its place in the customer's homes, but it's way too early tell how much effect the 360 will have on Sony's marketshare.
