Sony will be showing off more about PS4 at Gamescom this year, starting with a press conference before the world's biggest games show. The platform holder will once again host its conference on the Tuesday before the show (August 20th), returning to the Saatenhaus am Rheinpark in Cologne. The conference will kick off at 7pm Central European Time (6pm in the UK), while doors will open at 6pm CET. Sony has previously used the Gamescom press conference to announce price cuts for the PS3 and new line-ups for Vita, but the world will no doubt be hoping for more details on the release of PlayStation 4. Rumours suggest Microsoft may also be holding a press conference at Gamescom but these have yet to be confirmed. We are almost certainly going to see Gran Turismo 6 in the action so stay tuned! What do you guys expect to be shown about GT6?
