A couple of days ago, we heard that Quantum Break was going to be skipping E3 in favour of Gamescom this year, leaving the door open for more content at E3.
It seems Microsoft have a lot of games to show too, because Phil Spencer has stated that Platinum Games's Beats headphone dragon slayer game, Scalebound, and Crackdown will be skipping this year's show. Both titles were announced last year as an Xbox exclusive, but will be absent at the conference in LA for a spot in Germany at August's Gamescom.
