Can Halo 4 sell 4 million first week?

According to NPD, Halo 3 sold 3.3 million its first week, so I'd say with the larger install base, 4 million is very likely.

 

I think with the title "Halo 4" (for me VERY unlikely) it has a chance, but anything else will have less first week sales numbers than Halo 3
