Why everyone in the industry is so secret ?

Because the industry is not as healthy as advertised outside of the top few franchises.

If they refuse to breakdown game grosses, it's because most of them didn't profit
If Sony refuses a country breakdown, it's because it would show weaknesses

That's very true. The few times we hear publishers mention exact sales and how much revenue they made is when said games become insane successes, like GTA V, CoDs, etc.
