They developed MW2 for 3 systems so of course its going to cost more money than for just one. As for the marketing that sounds like that may be a little wrong. I don't know what Halo3's marketing cost but it was everywhere so I don't see how MW2's cost more.
But I guess Microsoft made deals with a lot of companies to cross promote so that may be why it cost less. Lets not forget that things cost so much more money now days than they did just a few years ago. Minimum wage increased so every company has to pay more now than they did as well. So who knows, its possible.
I am also pretty sure this $ was just a drop in the bucket and IW and Activision would be willing to drop this much on 10 more games if it did this well.
