All in all, I have found research about this industry hard to come by from sources that businesses would like to see. Forbes, Dunn and Bradd Street, Wall Street Journal, etc etc. Seems like the media only does research on video game companies when there is something like "Video game revenue to top movie box office revenue this year" and even this is a side bar to any of the big stories. If you find a site or a publication that has sales figures like you requested please post it here. It will make every business plan we create better.
