The new UI puts conversations at the top with a Metro-style appearance. Skype said, however, that the redesign is more than just a new UI - it's an entirely new app focusing on speedier instant messaging and easier access to contacts.
Nothing on a new iOS version, but Skype did say that "this was only the beginning" and that it will have "more updates in the coming months". Make of that what you will.
New look this, upgraded that, stick with whay you know - stick with our blips
