you can also estimate how many copies games that recently came out will sell.                                                       

games that have already come out

uncharted 2 ~4m 3.5m, but if it has the same legs as the first, 4-4.5m

forza 3~5m 3.5-4m

modern warfare 2 360 ~9m 12-14m

modern warfare 2 ps3~6m 7-9m

left for dead 2 ~4m I agree

halo odst ~5.5m(i think when reach beta is about to come out sales will boast. I would agree

games to come out

mass effect 3m 4m

splinter cell conviction 3.5 m 3-3.5m

god of war 3 3m(god of war did 3m and 2 did less) 3.5-4m The hype among PS3 owners is huge

allen wake 1.5m 2m I think this could surprise us

heavy rain 1m 750,000. The market for this game is limited, however this could be a sleeper.

fable 3 3m 3-3.5m

battlefield bad company 2 4m for each console 2m for PS3, 3m for 360 give or take a half million for both consoles

gran torismo 5 7m 10m This game will be big across all regions and would likely be the best selling PS3 game this generation.

halo reach 13m 10-13m I agree, this game will be big and 360 owners love them some Halo.

avp 1.5 m(for each console) I've never actually considered it, so no comment.                                                                                                                                      

Modern Warfare 2 to sell 4 million on ps3 tops? It is already at 3.95 million at the end of Black Friday week. You saying between Black Friday and MW3 it will only sell 50,000 units? That is the worst prediction I have ever seen.

To say Uncharted 2's sales to date have been "very dismal" is a terrible assessment. It is around 1.8 million already and is set to do ~2.25 million by year end. That is by no means a "very dismal" showing.

Alan Wake 2.9 million vs Heavy Rain 1.6 million? You say that HR is a "niche game for niche gamers"? The same things could (and perhaps should) be said about Alan Wake at this stage, as it is by no means a completely mainstream game.

Bad Company 2 to sell 2.5ish times on Xbox 360 vs PS3? Considering at the last update it was more like 1.75:1, I think 2.5:1 is pretty absurd. PS3 userbase is closer to 360 in terms of ratio now, and BFBC2 beta is on the PS3.

Gran Turismo 5: 3-5.5 million? You are figuring it might sell less than GT5: Prologue? Just what the f....?

AVP to sell 4:1 on 360 vs PS3? I can only see that happening if the sales are in the region of ~200000 for 360 and ~50000 for PS3, in which case it has no significance whatsoever.

L4D2 4-4.8 million? So double the original? Seems a little excessive to me.

Mass Effect 2: 7 million? Why...just why?

Forza 2 did 4m WITH bundles. Without heavy bundling, I don't see Forza 3 doing 4mill. Graphics WILL NOT translate into sales either.

Ahem...

I try to low-ball on many of them....more so seeing that after the xmas season I think certain already out titles will not be selling like hot cakes anymore.

I most certainly didnt realize that I had put 4milln mw2 for ps3...so scrath that. and toss in about 6milln...I just dont see it doin more than that regardless of the install base of the ps3.

As for BF2...I just don't think it will do that well on ps3..and thats just my opinion..don't like owell.

AW is more mainstreamed than HR....*even thou I'm more all for HR* therfore I felt itll sell alot better than HR.

Uc2...yup...for the critics to the rabid fans...its current amount sold isn't that great...more so when compared to other equaliy hyped/advertized games.

I do think l4d2 will do double than lfd1....hell...take a look at its sales so far.

GT5....I was just putting a guess even if its compleatly wrong...to be honest It could sell great and then again...be a fail...time will tell...take a look at gears of war 1 vs 2....and thats how i feel about gt.

Avp will bomb...Im not even sure it will get any sort of sales...not even thinking it will reach 1milln.

ME2...why you ask???...well...I think it's gonna be quite the seller. And you never know.

Didnt realize that youd be a lil upset just like a few others if someone low balled/highballed some numbers..so glad this forum is open to all to post.

In addition:

Final Fantasy XIII: 6m for the PS3, 5m for the 360

Of course these are rough estimates and will change.
