OP talks about revenue in Xbox department doesn't it?
Every Nintendo and Sony Q and Y earnings, the sales of HW and SW are discussed even if the title doesn't say Consoles Sold.
And.. Does MS have to be like Nintendo and Sony? You seem very interested in knowing there hardware sales.. why? so you can bash and compare them? MS know the negatively behind simply petty sales figures, that's why they stopped posting them, and as long as there are people that treat sales figures as a negative towards a brand, they will continue to hide the figures. It does nothing for them and there customers.
