wrong as usual. the fw buyers were probably people who already owned the wii u, since the hardware didn't raise that much on that week. but as the weeks pass and sales keep respectable levels, with hardware sales even getting higher than 3d world's weekly, it's obvious that a big chunk of 3d world customers are now new buyers.
Wrong as usual? LOL I think you'll find you're the one that gets things wrong, (see: every past prediction you've ever made )
