Sony is expected to unveil its next-generation home entertainment video game console at a press event on Wednesday. Reuters

The alleged Playstation 4, Sony’s next-gen console, is rumored to be unveiled at an event on Wednesday. But before that event, if it happens, details have been leaking out about the console -- the latest news we've heard is about a redesigned controller said to ship with the PS4.

Destructoid released leaked images on Valentine's Day of what it says is the controller for the PlayStation 4 console. According to the images, the controller is similar to PlayStation 3’s DualShock 3 wireless controller, but with some key differences.

One of the biggest and most obvious changes in the supposed photo is the addition of what seems to be a touchscreen interface where the “start,” “select,” and “PS” button is located on the PS3 Dualshock controller. In addition, a blue light is located at the top of the PS4 controller, which EuroGamer hypothesizes is the PlayStation Move tracking light.

“A closer link to the work of Marks and his team can be seen in the big blue rectangular light on the top of the pad, strongly suggesting that not only will PlayStation Move return for Orbis, it will actually be integrated into the Dual Shock itself,” Eurogamer said.

This implies the PS Move and PS4 controller will be combined into one product, which could be a benefit after seeing how successful Microsoft has been with the Xbox Kinect and the rumored plans for the Kinect and the Xbox 720.

Destructoid released another photo on Thursday as well, showing a different angle of the alleged PS4 controller. Located on the bottom of the controller is a small port that looks much like a headphone jack. Perhaps Sony will put a headphone jack in the controller to easily plug in a headset so video gamers can communicate more easily.

Lastly, the rumored PS4 controller will also have a loudspeaker in the center of the controller, directly above the PlayStation logo. The integrated loudspeaker feature is similar to the Wii-Remote, and could show how Sony’s trying to keep up with other console features included in Nintendo and Microsoft’s next-gen consoles.

Rumors about the PS4 have been flying since Sony released a video announcing its undefined event on Feb. 20, which showed the Playstation logo at the very end of the brief video clip. Recently, we reported the PS4 might be priced at $400 in the U.S. Major Japanese newspapers like the Ashai Shimbun and the Nikkei Business Daily reported the price for the PS4 might be 40,000 yen, which roughly translates to $400. It seems like a smart move for Sony, which suffered from poor sales when the PS3 was initially released in 2006 because the $599 price tag was so high. However, as soon as Sony dropped the price for the PS3, sales started to pick up.

It’s important to note that none of the information above has been confirmed by Sony, which remains adamant about not commenting on rumors of potential products in development. There’s no certainty that Wednesday's event will be related to the next-generation console -- that Playstation logo at the end of Sony's video could mean anything Playstation-related -- but considering the exceedingly long time since the last generation of consoles launched, as well as the growing competition in the gaming market in 2013 with the introduction of Android-based Ouya, Valve's Steam Box and Microsoft's own next-gen Xbox console, all signs point to a PS4 unveiling on Feb. 20.
