There is definitely a issue of disposable income. The overwhelming majority perhaps ninety percent of gamers simply cannot afford to multi platform on this scale. While the ten percent might make up a larger percentage of PS3 owners. I think your probably still only looking at a small margin of gamers that can actually own two or more consoles when one of those consoles is a PS3. I would say it is most likely isolated. I have only met one PS3 owner in real life and they did not even buy it for the games they bought it as a media hub. A non gamer as it were they own no other consoles.

Did you even bother to read the topic? I understand your from Mexico, but your comments do not match the thread in the least. Just curious blanket optimism is a good way to bring the trolls down upon a thread.
