According to new PR for Sony's upcoming CES showing, Skype is apparently coming to the PSP.

Details are scarce at the moment (i.e., nonexistent), but the company makes clear mention of a Skype client for the handheld game system on its CES 2008 promo site, which is pretty official -- though we're gonna hold our breath a little till we see a press release. Obviously, we'll be hearing a lot more about this when the big show kicks off this month, but until then at least we can all sleep a little better at night knowing the PSP is about to get yet another succulent function. Just hit the read link and click on the controller icon, all you need to know is listed in the sidebar.

Update: Thanks to some sleuthing by the crew over at UberGizmo, a perverse and exciting little easter egg has been found in the PSP promo video which accompanies this new info. For literally one frame, Sony all but confirms Skype on the handheld with a nearly-subliminal image that reads "Make calls with Skype." Check the image after the break and see for yourself.
