Don't think that I'm defending Bungle, but I've never seen any sales figures by unit, at all. 50M is an impossibility, with 30M RU for D1 and under 15M RU for D2, with free giveaways on all platforms. If you're going to present data, please back it up with a source. I cannot, nor have I ever been able to, find ANY sales figures beyond estimates made around launch, or estimates made thanks to the sales figures presented in O'Donnell's lawsuit.
