Considering past sales I think it's definitely probable. Some history -
MGS (PSX) - 6 million +
Halo (Xbox) - 5 million +
MGS2 (All formats) - 8 million + including Substance
Halo 2 (Xbox) - 8 million +
MGS3 + Subsistence has sold 5 million, which I think should be compared to Halo wars considering it's a prequel.
MGS4 vs. Halo 3 is on.
