Each Sony system has gotten revisions over the course of its life- the original PlayStation became the miniature PSOne, the bulky PS2 became the svelte PS2 Slim, the PSP got four revisions over the course of its life, each of them different takes on the original, the PS3 got two revisions and one rebranding, and the Vita recently had two variants released. So it follows that some where down the line, the PS4 too will have a revision of its own, possibly a slimming down. But of course, that won’t happen now. The system isn’t even a year old yet, and Sony can barely keep up with the demand of the current model as it is.
So that is why this new filing for the certification of a new PS4 model in Japan comes as a bit of a surprise. The new model number is CUH-11xxA, and its certifications seem to indicate some change in the wireless equipment within it… but that’s all that has changed, from what we can gather.
This might nor be a full fledged cosmetic overhaul like the PS3 Slim or the Xbox 360 S were. It’s more possibly just a minor reshuffling of the equipment, that has necessitated a re-certification. But Gamescom is right around the corner, so we’ll find out soon enough anyway.
