Due to the decrypting of a firmware last February and Sony’s unveiling of Go! Messenger in August at Leipzig, all indications point to the PSP having Skype functionalities released for it soon.
The official "unveiling" of this VoIP function coming to the PlayStation Portable may come as soon as this weekend’s Consumer Electronics Show in Las Vegas. On a special section of Sony’s website, the company details the events they will be conducting at this year’s CES and include an interesting feature not previously mentioned anywhere.
Sony lists this new feature under the PSP System Features column as "Call friends, talk trash to fellow gamers or catch up with acquaintances via Skype for PSP system." The website clearly states this as a feature that is presently available on the system even though it has yet to make it to the handheld.
Although no official word has come out on this, it seems like only a matter of time before Sony reveals this as a new feature in an upcoming firmware update.
The International Consumer Electronics Show (CES) is a trade show held each January in Las Vegas, Nevada, and is sponsored by the Consumer Electronics Association. The show will be running this weekend so stay tuned for new updates on this and many other updates that may come up throughout the show.
