Sony likes to release updated versions of its gaming systems that are a little smaller and more efficient. We already have the PlayStation 3 Slim, but now it looks like an even smaller version could be on the way. A recent filing with the FCC mentions a 4000 series PS3, which is an update over the current 3000 series (PS3 Slim). No exact dimensions were listed in the filing, but a rumor is going around this will be a super slim PS3 that will somehow be even smaller than the current one. The rumor says Sony will announce the super slim PS3 at Gamescom next month, which could have some credence considering that is where Sony announced the PS3 Slim in 2009. At E3 last month, Sony's Shuhei Yoshida did not confirm or deny an even smaller PS3 could happen, so take from that what you will.
