Of course, the real issue that groups like NPD and MediaCrate have with VG Chartz is that they've disrupted their industry. Sure, VG Chartz isn't as accurate, but it's also free and updated weekly instead of monthly. And it has built-in tools to gauge how well products have done compared to each other in a huge number of ways, something that I don't think any other tracking firm offers (let alone at no cost to the user). Most people will gladly take more frequent but less accurate updates that are free over less frequent updates that somebody has to pay for that are more accurate. We want the sales figures to speculate on, not picture-perfect accuracy of them. That'd be nice, but it's not as important as having the data itself.
Sky Render - Sanity is for the weak.
