A little more information has come to light in a blog
by Frank O'Connor, the Franchise Development Director, at the official Halo website
. Not only has 343 Industries
been working on continuing an already legendary franchise, but they've been developing new ways to implement it, as well.
But we’re not just making a new game in that three year span, we’re also making a new engine. During the development of Halo 4, we pushed the Xbox 360 and the engine to its limits, and we were happy with the way we were able to make the Halo universe look. The Xbox 360 still has a few tricks up its sleeve, even now. We are moving to a whole new platform with the Xbox One – a new architecture, new graphics hardware and bluntly some new ways to think about gaming, period.
If the one new image we have is anything to go by, whatever they're doing is working.
We also have a very brief but intriguing tweet from Josh Holmes, Executive Producer at 343:
For everyone speculating about the mysterious Spartan in Halo 5: Guardians, he’s not Palmer (or Cortana!). He’s a NEW character. :)
Who this mystery Spartan is, however, is still....well, a mystery.
That's all we have so far. Some major announcements are expected at E3; we'll keep you posted.
