In an interview with Edge Magazine, Sony Computer Entertainment president Shuhei Yoshida explained that when the Next Generation Portable device is released, it will not immediately take the place of the PSP on retail shelves. At least, in a physical sense it won’t. Yoshida said that the NGP “can’t replace a platform that has already been on sale for seven years now,” but then revealed the real reason why the PSP won’t go away so fast: “In terms of pricing, we can’t sell the NGP for the same price as a PSP.”
That makes more sense, doesn’t it? Sony’s situation with a new portable item replacing an older model is reminiscent of Nintendo claiming the DS wouldn’t replace the Game Boy Advance. Of course, it eventually did, but the initial price difference was enough to keep both products on shelves in the early going.
