Current PS3 versions are tagged with the 3000 series, while the new PS3 models will be labeled the 4000 series. The CECH-4001X model is mentioned and rumor has it that this pertains to a slimmer PS3 which will be revealed at this year’s Gamescom.
The new 4000 series model shows a new FCC label position and you can see it below.
Keep in mind that nothing’s official just yet. This supposed “super slim” announcement at Gamescom is just a rumor for now. We’ll have to wait till August to see if this is the real deal or not.
