Ok, two things, One: This is old news man, I bet everyone reading this thread has seen the page, and Two, gods_hitman-01 could be correct (Besides the bad grammar).
The sequel to black ops has been speculated to take place in the future, rather than in the past, though, black ops did very well, and a direct sequel is VERY possible, another reason I believe this, is because the Cold War is a very unexplored war, and would give the developers a lot of freedom. You guys should also know that Treyarch enjoys doing history games by now as well.
BUT... The loading screen is seems very Holographic, and not very old, so I think its open for Opinion on this one guys!
What do you think...
