Sony has something very big planned on February 20, 2013. So big that it is holding a special teaser trailer for the event before it is even announced.
 
Everyone is of course hoping for a PS4 announcement, or a glimmer, or just a confirmation. Sony has of course been working under the codenamed ‘Orbis’ for the next generation PS3 but has not revealed anything about the console up to this point. Breaking the news that it even exists before E3 could be a huge announcement from Sony, though the company has built up announcements that didn’t live up to expectations before.
