I found this post via a RT on Twitter from Ducain23.

A NEoGaf. Forum member makes a comment saying they think the Halo TV show by Speilberg has been cancelled.

Frank O’Conner, under his screen name there, posted this response:

Okay, so it’s not much, but it’s also not nothing!

So with this in mind, I 100% expect to see something of this from E3 next week!!!
