I hope we get to see something from Bungie...
I think that they think that we think they are not as relevent without their 'Halo' franchise. They even said in their ViDoc that they are 'starting over again' with their their new IP... and with pressure placed on them to emmulate the success of Halo with their future work; I think they might be overwhelmed in trying to fill in that order.
If it is a question of the developer's relevance and importance in the industry; their newer game should appeal to casual and core gamers alike.
What will ultimately determine their long-term success is the community that is based around their new IP... and how much were exposed to it on social media and what not. If all Bungie fans made Original (good quality) Youtube Videos (blogs, film shorts, art) based around the game, it will elevate player's perception and have players stick with the game rather then move on to something else (that has more Youtube videos about it).
Anyways... Happy Bungie Day!
