All data taken from Major Nelson. By the time MW2 hit, ODST was dying, and never charted in the top 10 after MW2. Uncharted 2 was released a month later and was still in its prime when MW2 was released.
I think you are being intentionally obtuse. Your original point was deflecting the lopsided MW2 sales ration by petitioning that UC2's "success" was slowing initial sales.
Have you seen Uncharted 2's sales
You can ignore the fact that ODST MP is a "Halo 3 MP disk" but you cannot ignore the fact that 1) Halo 3 is the top played game in 2009 on the 360 and 2) that this, too, would compete with adoption of yet another FPS.
Applying your logic, if UC2's "popularity" diminished MW2 launch sales, then Halo 3 which is the most popular shooter on the platform and just sold another 4M+ units via ODST -- maybe, just possibly, it would have the same effect ::cough::moreso::cough::
And it isn't even just that: the 360 sells a lot more software and has a LOT more online competition. The PS3 has nothing like Halo 3 in terms of online activity. CoD4 and WaW are far more popular on the Xbox to this day, and you still have titles like Gears of War 2 kicking strong. (And it isn't just games grabbing at online time, as my que of friends constantly on Netflix shows).
Really, your entire argument is bogus.
Halo 3 (which is ODST MP) is way more popular on the 360 than Uncharted MP is on the PS3. Uncharted 2 MP cannot be used as a cause for diminished MW2 sales in the light of ODST(Halo 3s) continued dominance online.
I think the general consensus is pretty clear on this one: The 360 has more shooter fans, more hardcore early adopters, and more online activity. MW1 was technically better on the 360 and has a much stronger community and the 360 in general has a strong software adoption among the type of consumers picking up MW2.
Gears (2006), Halo 3 (2007), CoD4 (2007), Gears 2 (2008), ODST (2009), MW2 (2009) form a pretty compelling trend in terms of the strength of shooters on the 360.
Great exclusives on the PS3, like UC2 and KZ2, just are not in the same
sales league. Call it demographics or issues with the titles appeal to the shooter audience, the bottom line is the 360 owners EAT SHOOTERS ALIVE. That idea that the relatively middling sales of a UC2 compared to an ODST impacted MW2 sales then the same needs to be applied and amplified to the 360 version.
The tip toeing around the software sales is ironic. First there are all sorts of reasons why UC2 and KZ2 don't replicate CoD4/Halo 3 sales when the install bases were similar, but now those lower selling titles are the reason for a dent in software sales of major selling franchises (MW2 on the PS3 will best both of those titles in lifetime sales) with a total disregard for the impact on the other side of the fence?
