I stopped reading the article when the guy asserted that the Xbox was a huge success after marking the Gamecube as a dismal failure. I get sick of reading articles or blog posts from people who understand less about the business of games than your average VGC poster.
Sony doesn't need to market their motion controller, they need to develop a killer app for it and market that. Arc/Gem/Wand/Dildo sales will follow after that. It can be killer for the 'cores,' killer for the 'casuals,' or killer for all gamers, but it has to be fresh and it has to be great or it won't even outperform the Eyetoy (which was a bigger success than most people give it credit for).
"The worst part about these reviews is they are [subjective]--and their scores often depend on how drunk you got the media at a Street Fighter event." — Mona Hamilton, Capcom Senior VP of Marketing
