The D conference is in full swing, and the next heavy hitter on deck is Sony CEO Howard Stringer, who's rumored to have a new Sony OLED display for Unkie Walt to play with. We're assuming it'll be a little bit bigger than the XEL-1, but Silicon Alley Insider says it'll come in at just .3mm thick, which is only slightly beefier than a playing card. We're guessing it'll be more like the XEL-1's 3mm, but we'll see what Howie has in store for us -- we wouldn't be opposed to hearing some more about those "slim PS3" rumors, ourselves.
