c'mon give me an estimation more concrete, realistic and convincing than mine.
I can't be completely wrong here.

Well, as a company they directly employ just under 3600 people (http://www.hd.square-enix.com/eng/company/outline.html)

Note their revenue figure in there (155B yen, or ~1.3B USD). According to their own financial statements they profited just under 11B yen from 31 March, 2014 to 31 December, 2014. That works out to just over 90M USD in profit for the last 9 months of 2014. That was after shelling out over 5B Yen (~45M USD) in taxes alone. They also had over 16B yen (~13M USD) in combined liabilities to account for. You can review the reports yourself if you want:

Percentage-wise, they aren't retaining a gross amount of revenues if you compare the figures to other players in the industry.
