To play pirated games on, for example, an Xbox, requires physical modification of the console itself. This leads to your online account being banned if you ever try to play games online with that machine.
So...requires money and effort just to be able to play pirated games...plus the fact that you can never use it to play online again.
Compared to PC piracy, where it takes just a couple of clicks to download a torrent of a new game, and this does not prevent you from playing other non-pirated games online if you wish. In fact you can even play some pirated games online depending on the level of anti-piracy stuff.
It's a lot easier to pirate stuff on the Nintendo Wii and DS, but less people using those consoles are inclined to piracy (well, the Wii at least). I don't know for sure about the PS3 but I assume it's something similar to the Xbox, where once you have altered your console either physically or via some kind of software hack, you can't use it for online stuff anymore.
In conclusion, it's ridiculous to suggest that console game piracy is as prevalent as PC game piracy. Only a small percentage of console owners bother to hack their machines to play pirated material, because of the effort and downsides involved.
Ack-Ack, I don't see how your mention that your companies' game released for Xbox and PS3 was pirated roughly 1/3rd as much as it was sold is relevant

no one is saying that console piracy doesn't exist....just that it is not as common as the pirating of PC games. I am just pulling this suspicion out of my bum...but I would strongly suspect suspect that for a great many PC games (especially single player ones) they are pirated by as much as 50% of people and paid for by the other 50%
