"Although we are still in the pre-alpha stage of development, everything you see in the video is in-game and in real-time running at 1080p and a stable 30hz. It's looking pretty spectacular already and we still have quite some time to optimize and refine our technology to make this the best looking and playing Uncharted game to date," PlayStation announced this weekend. "If you're wondering who called Nathan Drake 'little brother' and exactly what that means, we'll be trickling out more details soon. Why is Drake on an island? What's he searching for? Who's shooting at Drake again and why is he shooting back? Be sure to pay attention to our Twitter feed and social channels for the latest news and updates. 2015 is going to be awesome."
