The next Uncharted, Uncharted 4, or whatever you would like to call it is the worst kept secret in games. It’s coming, it’s just a matter of when. GameStop Germany has listed Uncharted for PS4 on their website which may mean an official announcement is imminent.
Uncharted 3 was officially announced at the Spike VGA’s in 2011. If Naughty Dog plans to announce their new baby this year, that’s the event to do it.
