Last night on Destructoid, Dale North showed off for the first time when is believed to be the controller for the next Playstation console. For those who haven't seen it, I'll show the D'Toid picture directly below. To reassure people, multiple sources from multiple members of the gaming press have had personal confirmation that the controller is indeed a prototype otherwise I personally wouldn't be reporting on this story since gaming media has seemed to be flooded with next generation consoles or devices over the last several months.
As you can see above, the controller looks very similar to the Dualshock 3 Playstation 3 controller except it's wider. Featuring a light on top and a screen on the front, there are a lot of updates that many people will overlook. First of all, the convex analog sticks are gone. I was a fan of them but I guess there is enough demand as the Xbox 360 controller has concave featuring a lip on the outside to give gamers a little bit of extra grip. There is what looks to be a touch screen on the front and even a Playstation Move motion control light. Instead of needing those dorky looking wands, you'll just use your controller instead which sounds good to me.
Looking at the sholder buttons, I notice that they are set a few millimeters back which won't effect the casual gamer but might take a little getting used to for a hardcore Playstation fan. Something that was rumored that might just be for testing purposes is the share button which allows you to transfer a video file from the PS4 dev kit to a normal computer for further analysis. I don't see how Sony would think it would be a good idea to use the CPU to record gameplay directly to your console. The last two things are the controller speaker and the touch screen. The speaker if I'm to guess will probably perform some of the same functionality as the Wii's WiiMote giving off terrible sound clips that reminded players that it was their turn during Wii bowling. The touch screen was first rumored to be on the back of the PS4 controller just like the Vita, but the Vita's front screen also has touch capability.
To finish off the breakdown of the controller: at the bottom, there is a headset port, which you can see better from the picture above from onehitpixel.com, that might be available for those people who don't have BlueTooth devices because those things weren't cool passed 2007. As David Howard said on his post from this morning, February 20th can't come soon enough!
