The game some people begged for, and others prayed wouldn't exist, is currently being worked on by Naughty Dog.
Work on The Last of Us Part II has just started, but a trailer for it did show up at The PlayStation Experience.
My Two Cents
It will be interesting to see how the general gaming public reacts to this in the coming days. While some really wanted a sequel to the beloved game from last generation, many hoped it wouldn't get one due to, what they called, a perfect ending for the game. Personally, as someone who never played the first game, it would have been more interesting to put the focus on another character in the same world, but that's just me.
