I'll throw in my two cents on the whole MAU vs non-MAU metrics or whatever. But I'm not interested in debating about it.
On the topic of financial transparency, both MS and Sony are pretty shit, actually.
MS more so than Sony due to the lack of HW numbers, but both aren't anything to praise about either.
Both companies should be sharing every single sales data they can disclose, all the way from individiual sales of every game they publish, MAU, hardware sales, accessories sales, etc.
Both companies could learn a thing or two from Nintendo. And even Nintendo, in terms of openness of biz information, is what I would call at best B-tier.
Capcom is a far better company when it comes to clear and honest investor relations transparency. Their website clearly details a catalog of their historical sales for all their products, they are updated quarterly and they show quarterly update of their key sales.
