Lots of great questions about E3, I am jumping over to Reddit to answer further Qs. Hit me up there:
Q: What do you think Microsoft's focus will be on when it comes to Xbox related news? Are you expecting to see any sort of gameplay from campaign or multiplayer from Halo 4?
Geoff: Yes, Halo 4 is a big focus for Xbox. We've announced that you'll see the first real campaign gameplay in the Xbox press conference on June 4. And then that night, in our primetime special we will be showing off Spartan Ops mode for the first time. I was at 343 last week. We'll be sharing more about Halo at E3 soon.
Q: Kind of a boring question, but will Turn 10 be there with Forza Horizon? Not sure if you can answer that.
Geoff: Yep Forza Horizon is definitely at E3 - we've announced that as being part of the Xbox Press Conference on Monday. And Turn 10 will be with us in studio to do a demo as well.
Q: Are we going to see a full reveal of Unreal Engine 4?
Geoff: Yes, we will be unveiling Unreal Engine 4 during E3 week on Spike. I went down to Epic and filmed with Cliff, Tim Sweeney and the whole crew. Full half-hour special on the engine and tech.
Q: F-yes. Hopefully it will be a treat for people more into the development side and the gritty details, not just the "Those graphics are so graphic!". But I guess all that info will come out sooner rather than later anyway.
Geoff: For sure, we are showing off the editor and a lot of the tech. Very in depth, glad to hear you are excited!
