Microsoft has a ton of original TV shows in the works for the Xbox One, and no series has been quite so anticipated as the Halo show being executive produced by Steven Spielberg. But now, Variety is reporting that Spielbergs Halo may not actually be an Xbox exclusive — a decision that would mean Microsoft is giving up its biggest draw to Xboxs original content push. Even a small window would be a major loss for MicrosoftThe one added draw that Microsoft would be able to bring to the series is interactivity — a feature that its been pushing throughout all of its original content. Its unclear what the interactivity will be, especially if the show is designed for a traditional TV network as well, but that could allow Microsoft to still reap some benefits of Halos popularity without making quite as big of an investment as it otherwise may need to in order to get the series.
