We happened to be walking by the Sony booth, the massive Sony booth, this morning when they were rehearsing part of their press conference. In particular they were showing a slide that read PSP Video Download Service. Unfortunately, we didn't hear any particulars, but they did go on to say something about an upcoming FIFA tournament for the PS3 and I believe that the head of the FIFA might actually take the stage later today to talk details.
The press conference starts at 6:15 p.m. local time, which is 12:15 Eastern time, I believe. No clue if we will be able to liveblog it, but we will certainly strive to get the details up asap.
