It has been confirmed that Call of Duty Black Ops will in fact have a Barebone playlist. This playlist removes killstreaks and perks.
The video on Black Ops 1 shows some separate rooms, assets, and other features which exist outside of the boundary of the game.
From DownSights: "Black Ops is not Black Ops without Nuketown. Following the tradition of releasing Nuketown for Black Ops games, the new Black Ops Cold War game also offers a revamped Nuketown called Nuketown '84.
Nuketown '84 has the same dimensions and map layout except for the aesthetics. The map's aesthetics have changed to fit the 80s theme, with destroyed buildings and graffiti-filled walls compared to a clean 50s suburban neighborhood seen in Black Ops 1."

Finally, thanks treyarch for listening to the community!
No Killstreaks or Perks im in heaven! best news ive had all week and that Killzone 3 announcement drove me crazy
"Let me make it clear that by my mention of Barebones, I was in no way confirming that game mode. I simply mentioned that due to Vahn (Treyarch MP designer) eluding to that mode recently on the official forums.
While he did say that it would be quite easy to give us a mode with perks/killstreaks removed, nothing is confirmed and much time is left for things to change. ~ WePlayCoD"
