An unnamed source spoke to CVG and claimed that many of the controllers currently being tested by Sony's R&D department mark a rapid departure from the loyal DualShock, which has served PlayStation consoles for 16 years.
These versions apparently include new additions ranging from an integrated LCD touch screen to biometric sensors on the grips. A second source explained that Sony was supposedly trying to emulate the UI philosophies behind the Vita, and this is what inspired the whole touch screen thing.
Until Sony announces anything, it's best to take all of this with a huge pinch of salt. Having said that, even if the above does turn out to be true, it seems unlikely that the company would write-off the DualShock completely. It's much more likely that they'd still be able to be used as bog-standard controllers in a similar manner to how Wii Remotes still work with Nintendo's Wii U, with suped-up versions featuring some of the additions mentioned also available.
This is the latest rumour in what's been a busy couple of months for leaks linked to the next-gen consoles. Former AMD execs have been in trouble for allegedly sharing highly-sensitive details about them, dev kits have surfaced all over the place and Sony is meant to be taking steps to prevent you playing second hand games on it's next box.
With so many leaks coming thick and fast, surely it won't be long until Sony and Microsoft step out of the shadows to set the record straight once and for all?
