Microsoft is doing their thing at the moment.
Halo 5 trailerRecore trailer - Xbox One exclusive from Inafune and the makers of Metroid Prime. Sadly its a CGI trailer, no gameplay.
Dark Souls 3 was shown, but again I think it was CGI. Spring 2016, but I'm pretty sure its not exclusive.
Xbox Elite controller looks like it has some neat features, for One and PC.
Xbox One getting 360 backwards compatibility, which is their biggest news. Works with "100s" of games with 100s more to come. Stick the disc in your Xbox One and if its compatible it will apparently download the compatible version for you to play. No extra costs, also works with Arcade titles. I don't know all the details yet but there you go.
