In addition to plenty of details with regards to the Xbox One launch Microsoft will show one previously unannounced game at Gamescom in two weeks. No details as to what it is at this point, but normally Microsoft tend to announced European developed titles at Gamescom. Could it be Crackdown 3? Well, since the first two games weren't released in Germany due to their violent nature that may be a stretch. It could also be Fable IV or perhaps something entirely unexpected.
