What secrets are you hiding?
The last Bungie podcast hinted that the developer plans to make an announcement at this year's E3, specifically on July 14th. With rumors flying every which way, I run down everything that has been speculated on.
Halo 4 - Minus Master Chief
This whole thing started when Sarcastic Gamer reported that they had a source telling them that Halo 4 was already well underway at Bungie and that it was going to be announced at E3. CVG took it even further when their source told them that the aforementioned sequel would not feature Master Chief, the series' leading man.
The Peter Jackson episodic movie-game project was confirmed by Microsoft a few months ago. The game is supposedly a new chapter in the Halo story and has been described by Peter Jackson as a "filmiest game."
Well we know that Chronicles is coming for sure, so re-announcing it would be redundant. However, that doesn't mean that the announcement can't be a confirmed release date or something along those lines.
Remember this rumor from a few months back? EGM started it by telling us that the third-person shooter was being developed for release in 2009 and may or may not be part of the Peter Jackson project. However, they state that WETA, Peter Jackson's effects company, is "definitely involved." That bit of information leads me to believe that yes, if this does exist, it's most assuredly part of the Peter Jackson project.
So we have Halo: Chronicles, a possible Halo 4 sans Master Chief, and a possible Halo prequel. Hey, here's a crazy thought: what if they're all the same thing? Seriously, these are nothing more than vague rumors that could easily be the same thing: a new Halo game that doesn't involve Master Chief and is helmed by Peter Jackson.
Or, I could be wrong, and we could get 17 new Halo games in the next couple years.
