I think 3. 3 and triangles are a very special number and shape in the natural world. The 360 being part of this world, not out of this universe like the Wii will get 3.
I am highly skeptical of CoD: Black Ops reaching 10 million because as other posters have stated, Reach and other big name releases will compete for the same consumer's dollar.
Furthermore, after 2 ingame days played on the horrid experience that is Modern Warfare 2's multiplayer, I expect Activision to do another closed beta for Black Ops leaving the game riddled with glitches, exploits, bugs and hacks just like MW2.
This no open beta policy will be the death of multiplayer for the CoD series. I don't care if Activision has an open beta for the CoD game after Black Ops. MW 2 ruined it for me and I will never buy another Call of Duty game again, no matter who develops and/or publishes it.
However, I will be buying Battlefield 3 :)
