You are right on your premises, still that isn't put in the article, he just doesn't even know about sales when you see what he wrote. Much less about sales trend and historic.
I also like one quote that I just can't find that is from 2009 or so "Even if we stopped selling X360, PS3 wouldn't reach us".
Looks like both companies have said things they probably regret! Lol!
Weird, though. Like you said the Xbox 360 lead was never that big. It just took long time for Sony to overcome it.
