the number of people who do not have online for a 24 hour period are massive...people have jobs that take them out of town, and even out of the country, some people have jobs that keep them away from that stuff for more than 24 hour periods..
further more.. while the xbox still isn't for a global market, with its regional restrictions, many of those countries are in a situation where only the "trump" of the nation gets internet... while this may seem extreme, I have seen original exboxs being sold for $800 in 2006 in the iraq public economy (such as it was). fact is sony is a global product (it's build this way, right down to the voltage requirements), and psn is a global gaming community with over 30 million more users online than xboxlive..
take a good look at the current stock exchange due to the xb1 failure.
