That upcoming Halo TV show? Variety says that it looks like Microsoft and Showtime are going to team up for its distribution. If this goes down, the live-action show will show up first on cable, and then become available on consoles with some kind of enhanced interactivity.
It sounds like the two are slow to hammer things out as they're both venturing into uncharted territory with this production. Halo is a prized property that I'm sure Microsoft is taking the utmost care with.
