It seems not. Strange, I really would have expected stores to be clearing stock but it's still like 30£+ in most places...
As Lynx said, they're still selling quite a lot of PS3s. Also, margins on hardware accessories are smaller than boxed software so it's less likely to be discounted heavily.
That said, I picked up two official Dreamcast arcade sticks for something like a tenner each when HMV were clearing their old stock back in the day, but it was really dead in the water by that point.
