First week Killzone 2 sales surpass Halo 3's first week in EU?

[Dianko]

If MGS4 managed half of Halo 3's opening week, I don't see KZ2 having a chance at surpassing it. Given the larger userbase and the hype behind the title, I expect it to do around 600,000 week 1 in Others. But I don't see it doing GTA4 (PS3) or Halo 3 numbers.
