halo 4 is actually called reach it takes place befor halo 1 but is made after Halo 3 so you could call it halo 4 but its proper namee is reach and it is already out now.
sorry i don't remember the date but i put this over a guy who said somthing extemly pointless in time.. (thx have fun)
My answer. Technically the previous answer was false. ODST was #4, Reach #5. Since Bungie has made a descion to abandon Halo Microsoft Studios will possibly be realeasing the "next" Halo.
The previous answer is correct whereas the first is all wrong, 343 Studios and Microsoft Game Studios are going to release halo 4 as a lead on from where the master chief is trapped just as the arbiter goes through slipspace. It will be released in December 2012.
Halo 4 is called Halo 4.
Halo rights are owned by Bungee. Technically Halo 4 is "Halo ODST"
Yes, there is a Halo 4.
There is multiplayer in halo 4
there is no halo 4 because it is a trilogy. halo 3 was the end of the series.
halo 4 limited edition, comes with a copy of halo 4, a T-shirt and special armor customization.
Masterchief
No, the Arbiter is not in Halo 4.
Halo 4
In the Halo Universe, Halo CE. In reality, Halo 4.
Not yet, but there will be. Well, technically, you could classify Halo: Reach as Halo 4, but as for the actual Halo 4, its currently in development by 343 Industries.
Halo 5 will most likely follow the story line of Halo 3/Halo 4.
