Understandable if it's pushed to 2015.

But will it be 1080p 60fps is the real question

If they want it to look good, no chance. Right now 1080p/60fps is just not viable if you want to make a highly detailed game (more so on the X1 but the same point stands for the PS4).

Unless it's on PC in which case 2k/120fps all the way :D

Hope they announce Halo 2 and then 5 for 2015.

Was anybody expecting news sooner? I wonder if the great plan is Halo 2 Anniversary this year and Halo 5 next year.

No developer is pulling that off for graphically intensive games on consoles right now. They'll have to pick between 60fps or 1080p. Since it's an fps I would assume they'd stick with 60fps. 

^ & Zekkyou Well, this is Microsoft's real big chance to impress everyone and show what the xbox one is capable of... They have to do something to address the issue right?

I hope it's 1080p 60 fps so no one will talk about that and will maybe, just maybe discuss the game itself.

If I was a developer I'd be pretty pissed that everyone seems so fixated on resolution instead of actual gameplay.
