Take a look at this regarding GfK: http://abload.de/img/npdmarch2015finalt3yqu.png Here's an example of Microsoft citing NPD, GfK, and IDG for their figures:
There's an Aquamarine post in GAF somewhere where she explains how Sony gets its PS4 sold-through numbers which involves NPD, GfK, IHS, IDG, and Media Create/Famitsu. However, I don't even know where to look and I wish I bookmarked it for reference... |
Thanks for posting that. I can see why some of those are for the most part not mentioned in video game related media/sources. Some of those only cover tiny bits of the market. I trust that vgchartz WW numbers are an estimate and that brett often uses the big 3, NPD and other sources to adjust the numbers.
