If you can skype on your 100 million other devices that half the tech population of the world has does it matter? No a days people have smart phones, tablets, laptops, and desktops, so why do you need skype on your PS3?
I forgot to mention. Please vote for the idea if you haven't done so already.
Official response from Sony customer support: same old corporate baloney.
Thank you for your reply. As of right now we do not have any information as to when or if a Skype application available for download. I would recommend checking out http://blog.us.playstation.com/ for any updates regarding a Skype application. Unfortunately, I do not have any additional information that I can provide you at this time.
I would like to thank you for your time and patience in this matter.
