Several photos have appeared online showing what looks to be the PlayStation 4 controller. There's speculation that it's merely an early prototype peripheral for the next-gen system, but its design nevertheless reveals that Sony will likely not stray far from the (modified) form factor it introduced with the original PlayStation in the 1990s. Both Kotaku and IGN claim that it's the real deal (for whatever that's worth), and not something a Sony fanboy conceived for kicks.
Over on Neogaf, "Beermeister" has taken the time to point out some of the improvements like the rumored Move addition (the glowing bar) and an IR module. A built-in speaker or microphone can also be seen between the two analog sticks, just above the relocated PlayStation button. An audio jack for a headset looks to be mounted below and between the analog sticks.
The image also points to two buttons that are likely Start and Select which have been relocated to the top edge of the controller. Previous rumors also spoke of a "share" button for sending screenshots and video to social networks and more, but that doesn't seem to be included on this prototype.
A second photo emerged on Friday, showing an angled view of the controller compared to the previous photo's face-forward view. Here you can clearly see the audio jack between the analog sticks, the speaker/microphone, the relocated buttons and what's likely to be a white Move component at the top. This image appeared on the GameTrailers forums by an anonymous poster who "confirmed" that it's a PlayStation 4 controller.
There's speculation that the product shown in both photos is a mere prototype due to the "wired" connection. Of course, it's quite possible this peripheral is indeed wireless, and merely recharging or connecting to the host hardware on purpose. But it could be an early prototype for developers too as Destructoid claims… it's anybody's guess at this point.
