I have a flatrate, so I don't feel the bandwith costs directly, but of course increased traffic by every customer will influence the calculations of my internet service provider and they will in turn adapt the prices, for example not lowering them if they could otherwise.

I red somewhere that the transfer costs of 1GB is less than 5 cent currently.

Personally I've thought that the AAA game genre for any platform has been a bit boring for years now. All the consoles and PC's get the same, generic shooters year agter year while Nintendo keeps churning out Mario and Zelda. Can you really blame people for getting bored, if only new thing you get is a bit better looking graphics?
