I agree Zeus, but I imagine they see it in fairly black and white terms, and I'd imagine piracy rates are a HUGE factor in that calculation, so while it's painful the PC users have kind of brought it on themselves. the 360 suffers with piracy as well, but MS are at least attempting to combat it with every large release (loved the quote from the idiot who likened losing access to LIVE as the death of his dog, what a nutter). And as far as I know piracy rates on the PS3 are either zero or so low as to not be a consideration (anyone actually know more on PS3 piracy rates ?)
It's not helped that this is by Activision who are pretty aggressive when looking at finances, to the point they were happy to lose x% of PC sales with the console skewed game with no dedicated servers. Look though at the HUGE sales figures and ask them if they are bothered by those lost sales, I doubt they give a monkeys.
The place PC's beat consoles is in MMO's because there you can't pirate the software and have to pay monthly, all other genre's I think will lean more and more to console's being the main development skew. Dunno, maybe this will make people realise that you can't take something for nothing, without some consequences, but I doubt it. But then that said I only really thought about that properly when I released my iPhone game and saw the piracy rates for myself
