What's been confirmed, and what did we get a glimpse of? Microsoft announce that they would be releasing 15 exclusives over the course of the One's first year of launch - 8 of which will be brand new IPs. We take a look at a few of the launch titles, and those that will drop in early 2014.
Call of Duty: Ghosts
Same name, new game. Call of Duty: Ghosts departs from the Modern Warfare franchise and forms a new story, still keeping its roots firmly grounded in traditional CoD gameplay.
The game is set 10 years in to the future, after most of America has been destroyed in all out war. You play a Ghost - one of the last remnants of America's finest units, taking the war back to the terrorists.
The game utilises a brand new next-gen engine, which offers a staggering level of detail over it's predecessor. With all new combat moves, a script by an oscar nominated producer and a canine companion - this is set to be a sure fire hit.
Forza Motorsport 5
Possibly the worst kept secret in gaming history, Turn 10's next-gen racer is set to be an Xbox One launch title.
With advanced physics, immaculate detail and integration in to Xbox Live's new Achievement system, this is sure to be the best Forza yet. We didn't see any in game footage, or even a lot of a tease - E3 should be brimming with further details.
Fifa, Madden, NBA and UFC
EA Sports showed off their brand-spanking new in-game engine: Ignite. Featuring painstaking attention to detail, massively improved physics, dynamic AI and numerous social interaction plans - expect to see more of these at E3. Late 2013/early 2014 should be a cracking time for sports fans.
We knew Remedy were working on something, but nobody guessed that it would be a brand new IP. The Max Payne and Alan Wake developers showed off their Quantum Break trail which featured live action sequences filtered with in-game cutscenes which looked extremely action packed.
Remedy are experts at third person action thrillers, so this is one to definitely keep an eye on.
It didn't take a rocket scientist to see that this title would be heading to the Xbox One. After having it's lid blown off at the PS4 reveal, Bungie's massively multiplayer online FPS looks set to get the very best out of both next-gen consoles hardware and online services to create a 10 year long saga.
I don't know about you guys, but I'm really looking forward to this one - with Bungie's track record for attention to detail, Activision must be rubbing their hands already.
