Congrats to Sony on their incredible success. Regardless of anything else, PS4 has been a huge win thus far, and I don't think many of us saw that coming before the new console generation began.
I feel validated in my quest to understand precisely why PS4 has been so successful, due to Shu Yoshida publicly not being able to figure it out, either. Still, the numbers speak for themselves. Whatever Sony did or is doing, it's working.
Beyond that, I see absolutely no use or point in comparing sales to previous console generations. It serves no purpose, and trying to analyze it will cause your head to explode. Each console generation has it's own unique characteristics, software, and market conditions. Comparing Wii numbers to PS4 numbers is... completely silly. Other than the fact that they're both historic success stories, I don't see any other information to gleam from that kind of discussion. Wii was a casual market console, with low specs, and a fundamentally unique controller, and it had it's success long before the smartphone/ tablet market revolution. PS4 is very much an active gamer machine, with lots of social functions, that has a relatively similar controller to other consoles.
Bickering over who shipped more consoles, which data to look at, when you're talking about a console released in 2006 vs one released in 2013 is, again, utterly ridiculous.
