The big question is how much it's costing Sony to develop a 1st party IP for the PS3. It could be pretty bad, given the notoriety of the PS3's development....Difficulties.
However, on a $60 game, about $40 should be profit to the developer, minus retail markup, marketing, and packaging costs.
So on a $20m game (should be average for a PS3 title, but I'm gonna say it could be a little higher), they need at least 500,000 units to break even *provided* there aren't variables - they could make slightly less due to unforseen costs in an easy-cheezy $40 estimate for profits per game. It could be lower due to incentives or overseas costs, but should be a good average.
I'd say anything over 1m sold through is assured to make them money.
Back from the dead, I'm afraid.
