At the end of the Microsoft Press Conference at E3, Don Mattrick confirmed the "dawn of a new Trilogy for Xbox 360". He then went on to show the trailer for Halo 4.
The announcement of Halo 4 won't surprise anyone who's been looking at Twitter today - details went accidentally up on Xbox.com some hours before the conference. But we didn't know it was going to be part of a trilogy.
We'll get the trailer up ASAP, but here's a summary: it starts in what looks like empty space, but turns out to be the guts of a man. That man is Master Chief, and the female voice we heard saying "Please! Wake up, John!" was Cortana.
Before you know it, he's jetting himself around space debris like a ruddy hero, and basically surfing a broken spaceship. Welcome back, Master Chief - a million teenage testicles just created puzzling sensations for their owners.
