Halo 4 Nation
A while back, 343i stated that there will not be a Legendary Edition release of Halo 4, instead just a limited and standard edition. While I believe this news is set in stone, BS Angel seemed to hint at more possible Halo 4 branded releases.
In response to a tweet asking if there will be anymore editions of Halo 4 revealed, BS Angel wrote:
To me this seems to hint at a possible Halo 4 Branded Console release for the 360. This console will most likely will be detailed in Halo 4 graphics, as well as the controllers and mic that come with it.
