Looks like Sony will be unveiling something big on February 20, 2013 as they posted a teaser video on their website. It is very likely that this will be the announcement of the PlayStation 4, or codename Orbis, or maybe it will be a new lineup of games for 2013 for the PS3 and hopefully including the PS Vita.
But we are more leaning on the Orbis (PS4) announcement, rumors have been spreading about the console being in development for the past few weeks.
The announcement will take place in New York on February 20, 6PM EST and the event will be livestreamed.
Kotaku had some nifty information on the PlayStation 4 which includes its special features and an upgrade
