The 360 just refuses to roll over. Even when Devil May Cry 4 sold better on the PS3, the 360 version still budged itself to a million. There are also many titles which could become million sellers for the 360 very soon, so watch out for those.
As for the Wii, it has some titles which will take a couple weeks or months but will reach the million (Cooking Mama, High School Musical, sadly). The PS3 has Smackdown vs. Raw, which should hit a million after a while. The rest of the games are going to take some major hardware boosts (I've got my eye on your MGS4!) to reach a million. These are games such as Madden NFL 08, Army of Two, Burnout Paradise, and Rainbow Six 2. Not easy, but definitely achievable.
It looks like quite a strong market. The 360 won't give up its million seller lead anytime soon.
