Good points, but I'm still left wondering about the underlying math.
Yes, the console market is >> the PC market. Agreed. But the competiton is also much fiercer in the console market. GR2 for the consoles is competing against a wealth of other titles out there, while it would have a relatively open field in the PC market.
Now maybe the real numbers actually hold up, and you can make a console game that's like the other console titles in its class and still make a greater profit then releasing into an empty PC market. But I also wonder if the all the marketing guys are seeing the total size of the console market rather than what they can realistically get in that space glutted with other titles.
