o halo 4 is deff. coming in a few years. and it going to start off by that ship landing on that planet :)

Like someone already kind of said, there won`t be another Halo, but there will be something like it. For those of you who don`t already know, Marathon ended with the ``chief`` (you could say) going into hypersleep (like the end of h3). Halo 1 started with the chief waking up from hypersleep. Now, I think, the new Marathon (if Bungie calls it that) will start with the ``chief`` (or whatever character is used) waking up from hypersleep.

ok well the Halo movie is now officialy gone...universal and fox couldn`t work together....NOW that doesnt mean it`ll never come out...maybe another studio might take the rights

I think yes there will be a fourth Halo that will continue Master Chief`s story, but as Yakuza and many others said it wont be called Halo. There is a rumour that Bungie will name it Marathon, because Marathon was one of their first games they made, and it is tied into Halo. Except it will be a new Marathon about the Chief, besides too much money in Halo for Bungie not to continue it.

o and i very strongly think tht the planet in the background is onyx,the forerunner homeworld
