It's not exactly a well-kept secret that Sony's working on another console, but further confirmation has today arrived by way of an engineer's Linkedin profile.

Frederick Umminger claimed in his profile that as of 2010 he was working on "maintaining voice chat library for PlayStation 4", though the listing has since been corrected to read "PlayStation 3" instead. But was it a simple typo?

We don't know more until Sony announces their next console, which may or may not be called the Orbis. Apparently that'll happen before the next Xbox gets released, at least.

Is there a possibility this was more than a typo on the engineer's profile? What are your hopes for the PS4? Tell us in the comments or on Twitter.
