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!!!
