No reason to predict. And the name is Skillz - with a Z.
Seriously, I don't agree with darth hardly ever, but he/she is correct. If you or others think it's gonna have MGS/GTA 4 numbers, folks need to lay off the geezus juice.
I'm bookmarking this thread in the unlikely event that folks are calling it a success and it ends up nowhere near their predictions.
I'll go with 550K first week, max 2 million lifetime, if that.
If call of duty can reach 4mil, on ps3, Killzone 2 should be able to the same thing. There's bundle in europe too, so it's not that crazy like you think. It depends how it's advertised, of course.
My prediction is 600k first week and, 4 million lifetime.
