Halo 4?

According to my sources, there will be another Halo besides Halo Wars but it won't have Halo 4 as it's name. And it will have more blood like Gears of War and will be more tactical like G.R.A.W 2. And master chief will not be starring in it. Here are my sources:

Bungie is mot retireing and they will be working with Microsoft to make the next Halo game will be another Halo and I'm not talking about Halo Wars, but in this new Halo Game there will be no Master Chief in it and it's going to be more tactical like Ghos Recon Avanced Warfighter and it's going to have more blood in it like Gears of War

What we heard: Last year, those skilled enough to complete Halo 3 on legendary difficulty were treated to an extended ending of the game after the credits rolled. For those who don't have a knack for Covenant slaying, numerous YouTube videos depict how, after the defeat of the Flood, series hero the Master Chief is left adrift in space in half of the United Nations Space Command (UNSC) ship Forward Unto Dawn.
After a brief conversation with the AI Cortana, the genetically enhanced, perpetually armored Chief enters a hypersleep chamber. The cutscene camera switches to an exterior shot, which pulls back to reveal the remnants of the Dawn entering orbit around a mystery planet. As the sun rises on the planet, music swells, and the screen fades to white, at which point the cutscene abruptly ends.
With that setup, many assumed that Bungie's next project would feature the Master Chief marooned on a strange planet, struggling for survival--a sort of off-world Far Cry. However, a source with knowledge of the studio's development slate told GameSpot a different story. She or he said that sometime this year, Bungie will announce a "darker, grittier" Halo game that doesn't feature the Master Chief at all.
According to the source, the new Halo game will be a spin-off that resembles "a cross between Ghost Recon and Gears of War." It will reportedly tell a "less cartoony" and "more bloody, violent, and grim" tale of a battle between UNSC forces and the pan-racial religious empire known as the Covenant. The game's atmosphere was described as similar to that of the live-action Halo shorts directed by South African filmmaker Neil Blomkamp (pictured), who was to helm the now-stalled big-screen adaptation of the game.
The source says that the upcoming Halo game is a tactical shooter that will follow a squad of colonial marines or orbital-drop shock troopers engaged in "intense" fighting on the ground. Gameplay details were scant, other than the fact that it will reportedly let gamers play as an entire squad in co-op mode through the entire campaign. The exact number of co-op players has yet to be finalized, but it could be as high as eight. It is unclear if the new game is the same as the "Halo: Forerunner" project first rumored in 2006.
The official story: Microsoft had not yet responded to requests for comment as of press time.
Bogus or not bogus?: Based on the strength of the source, this is almost certainly not bogus. And with Bungie's teaser last week, news about the game could arrive as soon as tomorrow's Microsoft press conference at the E3 Media & Business Summit.

E3 2008: Bungie at work on new Halo
Loose-lipped Xbox head lets slip.

by Martin Robinson, IGN UK
UK, July 16, 2008 - The ongoing saga of Bungie's no-show at this year's E3 has been given another little twist, with Microsoft's Don Mattrick confirming that the now independent developer is indeed hard at work on another instalment in the Halo series. Speaking to MTV Multiplayer, the head of Xbox business said that the amount of content in Microsoft's conference on Monday squeezed out any news on the extension of the Halo series, and said Bungie is actively working on a new game that is neither Halo Wars nor the awaited Peter Jackson project. The news comes off the back of heightening speculation about Bungie's presence – or lack thereof – at this year's event, which climaxed in an open letter placed on the developer's website apologising for the no-show. Meanwhile, the countdown to its heavily touted announcement - which was expected to happen at 7:07am PST on July 16 - continues, though in light of the recent news many expect the deadline to pass without fanfare, or news of a fresh Halo title.
And I found this:

Here’s something to add to all the E3 drama this week about Bungie Studios‘ canceled/postponed/hyped debut of a new game…
In an interview shot for MTV News on Tuesday, Microsoft’s head of Xbox business Don Mattrick, confirmed to me that Bungie is indeed working on a new “Halo” game of some sort for Microsoft.
I had been asking Mattrick about the lack of “Halo” news at E3. He said that Microsoft’s Monday press conference was already loaded with content and so any announcements for that series weren’t needed to get gamers excited.
I pushed him on the lack of presence for the series and asked him if we should be worried about the no-show of Ensemble Studio’s real-time-strategy game “Halo Wars.” Not only did Mattrick say not to worry and that announcements would be coming, he also said that Microsoft is working with Bungie on a “Halo” game.
I asked for clarification, wondering if Mattrick meant Bungie’s project was “Halo Wars” or the long-announced Peter Jackson “Halo” project. Neither, Mattrick said. The Bungie game is something else.
And then, not surprisingly, the topic was changed.
In the coming days, we’ll have more from the interview — covering Microsoft’s courtship of Square-Enix and the importance of exclusive content and games in the future — here at the MTV Multiplayer blog
This game sounds awesome
