Just to bring light to the argument. In the financial report posted on one thread in this site there was only one type of cost, opperational, but they show the gross profit also, from wich we can take the production cost. SO you basically have the cost to publish and sell the the game (production) and the cost to run the company(operational). The diference is that the operational cost are incurred weather the game sell or not( part of the production cost too, but that´s not the point), so from the numbers provided you can take that the games achieve a gross profit of roughly 30%.
The thing is that most of the operational costs are probably of games still in production, like R&D, licenses, royalties, etc. and cannot be confused with the costs to make the games that are now generating revenue.
So, to say that console A or B generates more profit, you would have to get a special report with the separate costs of each game produced and it´s respective sales, to each console. Anything else is just wishfull thinking( I wish console B were the biggest money loser, or something like that)
