EA net income per plattform for the last quarter.

[kn]

These are "net revenues"... I'd like to see more data on how they got these numbers...

But on net income:

 If one platform is the "lead development" platform, the cost to develop will be far greater. To "port it" to the second platform is a far less costly event. I don't know how EA accounts for the cost of development across multi-plat titles but that could be a big factor. Imagine development of a PS3/360 exclusive "big budget game" -- say some big shooter. Assume it cost $40 million to develop for both platforms and the PS3 was the lead platform. The development of the game includes creative work, development, management, and so on... Say $30-35 million of the total was consumed in making the "initial" version and then $5-10 porting it to the 360. Assuming they make no "adjustments" to the cost of development for each platform to spread the cost of development and the titles both sell 1 million copies, clearly the 360 version will be more profitable.

I suspect they do "allocate" costs, but to what degree is anyone's guess. I wouldn't read too much into these numbers without knowing the breakdown of costs.
