When i logged in today i noticed that some of the patch looks like it has taken efftect. There is now Mercenary Team Deathmatch, Hardcore Search and Destry, and the map Showdown has been put back into the map roataion.
I have failed to see any changes in the sniper riffles and the ACOG scope (which really upsets me

.) Also they have not changed the running speed when you have the P90, and the kill cam's have not been changed.
Shortly after posting this, i went back to the xbox forums and looked for some more information, and here is what i got:
"[Clarification: Playlist changes coming soon (in December) patch won't be through certification till after December]"
