Hmm a couple of thousand, because its a Sony release and the retailers are all competing to break the street date first.

Well if it goes like that the Game would only Sell 75,000 its first week...the first one, when it came out wasnt very known, and the second game came out in 2007, people were not really buying ps2 games anymore and Ps2's pirating was at its worst . the 3rd also has Much much more hype then the last 2 . and chains of olympus was a spin off on a handheld that really never sold much software to began with, so Expectations are a little higher but your right, me included, we are getting a little ahead of our selfs , cant hurt too hope, right ?

about 700K

Under 500k first day.

us - 300k
Eu - 100k
Japan - 15k

First few comments in this thread are ludicris. More reasonable posters need to comment in here to put them in the minority.

First day WW : 800k

First week WW : ~ 1.2 million

I really have no idea. How many PS3 games have ever sold 1 mil in a day? I can't think of one. I'll go with 500k WW. It'll sell like hotcakes in the states, I'll say 350k in NA, 125k in EU and 25k in JP.

One thing I know is after playing 2, this has become a bargain bin game for me.

MGS4 and GTA4.

Also, not liking GoW2 means you have no soul.

OT: I'll predict first week, because it's simpler.

NA: 700k

Others: 350k

Japan: 50k

Total: 1.1 million

Then between 3 and 4 million lifetime.

Your stinging reprimand hurts my sou. . . no wait, I'm good.

North America: 550k

Europe/Others: 400k

Japan 30k

Total: 980k week one.

With a large drop off the following week

North America: 230k

Europe/Others: 160k

Japan 4k

Total: 394k week two.

true, and I do expect it to outperform the previous entries in the series first weeks.  Being that is the 3rd in a well liked series should boost it's sales on the front end (although it will probably hurt its legs).  I wouldn't expect more than 700k though first week, let alone first day.
