I disagree bundling first party software helps eat loss. Bundling third party would hurt them.
As for the ratio, MS simply has a more hardcore audience, and halo, which one out of 2 360 owners owns. If Resistance or LBP been as popular, the ratio would be much higher.
I think they are trying to offer as much value to potential customers as they can. Right now they simply can't drop price, bundling is the only way, and better to bundle 1st party than 3rd party.
What the graph does make me happy about is that sony has sold 15million games at 60$ a pop for their first party. That really helps recover costs.
I do agree that they have to come out with a lot more stuff though if they want to survive. Having some multi-millino selling 1st party titles might even permit them to price drop since they would offset ps3 losses.
It's really too bad for Motorstorm, Res2, and LBP, but then again, ps3 owners have a much more diverse taste than 360. You won't see 10m+ games on ps3 until there are like 50m consoles in the wild.
