With all the H4 info being released recently, I wanted to condense everything into 1 blog post.
Lets start with the Game Informer stuff, the main points of the magazine article can be found here: http://www.halotracker.com/Forums/ShowThread.aspx?ID=141572
- Sprint is always available, not a seperate ability
- Jetpack, Camo & Hologram return as Armor Abilties
- Forerunner Vision, a new ability
- Join in progress top prevent quitting
Taken out / Not returning
- No Elites in Multiplayer
- No Firefight
- No more respawn delay, tap X to respawn
- No more weapon camping, random weapon drops

All the above info has been confirmed by Frank O'Connor (http://halocouncil.com/content.php?55-GameInformer-Halo-4-Information-leaked! - bottom of this post) and David Ellis (http://www.neogaf.com/forum/showpost.php?p=36731047&postcount=14908)
In the recent Halo Bulletin (http://halo.xbox.com/blogs/Headlines/post/2012/04/05/The-Halo-Bulletin-4512.aspx) - Info can be found regarding H4 Cortana (seen on the front cover story of H4 in GI), & Network Tests being made.
