Jesus why are you guys arguing this, let me break down what he is saying:
1. The Xbox360/PS3 market is much bigger than the PC market.
2. For developers to ensure a profit they need to develop games for these consoles.
3. This profit requirement forces the technological side to be artificially pinned to whatever technology is in these aging consoles.
4. Because technology is pinned to aging consoles, all of that progress made in the PC department is basically idle hardware for the majority of the games being developed.
Now why is he saying this? Because this is a team that made a fantastic game for the PC that nobody bought. So now they are forced to make their sequel on consoles and they are probably frustrated with the hoops they have to jump through, the technology the basically have to GUT. Granted, the new engine is supposed to be flexible for this but I'm betting they have had a few discussions that went "wouldn't this be so easy if people just had decent fucking hardware?"
And yes, console developers tend to eek a lot of performance out of their respective systems. However, they often do it the same way companies are able to make cheap Rolex's. They make the exterior all shiny, but remove 90% of the functionality. That is why, even though you will see a lot of pretty games on the 360/PS3, you will never see a game that offers as much as Crysis did in so many different departments.
