Announced games on any systems which you think will do 1 million sales first week, I will go first.

1. Wii sports resort

2. Halo ODST

3. GT5

4. Modern Warfare 2 on 360

5. FFXIII on PS3

6. Versus

7. DQ IX

8. Diablo III

9. Starcraft II

10. Sims 3

And that is all I can think of. :D

WW of course, not in a single territory.

Why not MW2 on PS3? World at War came pretty close. FFXIII 360 should do as well.

Assassins Creed 2 is another one.

Id say MW2 has a high chance of 1million on PS3 also.

Gran Turismo 5

why is versus in there

if that does 1 million in week 1 I'll sell my PS3

DQX on Wii.

i don't see wii sports resort doing a million in a week

Assassin's Creed debuted to over 800k on the 360 alone, I'd say that one has a chance. Modern Warfare 2 is a given on 360, and could possibly make it on PS3 as well. Halo ODST is another given, and I even see a possibility for Madden given the userbase growth since last year.

Champions Online?
That looks really good

You will get a skittles packet in return by the time Versus releases but whatever, Japan alone will guarantee it does 1 million first week.
