Samsung on Monday said it plans to hold a press conference in London on June 20th to debut several new devices. The company issued invitations under the heading “Samsung Premiere 2013 Galaxy & Ativ,” confirming that both Android and Windows devices will be unveiled during the event. It is unclear what models Samsung plans to showcase — “Galaxy” covers Android phones, tablets and even cameras, and the “Ativ” brand includes laptops, tablets and Windows Phone devices, so narrowing it down that way is impossible. Samsung did include a few teaser pictures on its invitation though, and two of the images appear to show close-ups of a notebook computer. The teaser images follow below.
