Sony's PlayStation 3 is currently available in two flavours: the $499 USD 20GB version and the $599 USD 60GB version with 802.11b/g wireless networking and a MemoryStick/Secure Digital/CompactFlash reader. Based on a printout from Best Buy's computer system, it seems that the retailer has marked the 20GB PS3 model as discontinued. Joystiq confirmed the claim with three separate stores, and indeed it appears that Best Buy will no longer carry the 20GB model.
Earlier this week, Sony's David Karraker stated: "Overwhelmingly, retailers have been requesting the 60GB model, the mix has been about 80% 60GB, 20% 20GB retailer orders." According to iSuppli, Sony is losing $307 per 20GB console and $241 per 60GB console. It would seem that the logical choice for Sony would be stop production for the 20GB version: the 60GB model is the more popular choice and it doesn't set Sony back as much. However, Sony probably doesn't want to limit their customer's choice (Best Buy isn't helping) and isn't about to go ahead and make the price difference between a PS3 and a Wii/360 even greater.
