Three words, buddy: pot, kettle, black. Given your own grandiose assertions about what everyone in the gaming industry does or doesn't think, you ought to spare me your accusations of hubris. Reality check: if you're gaming on every console and six different PC's, you're pretty much an aberration, not part of a demographic. So, unless you wish to contend that your Batcavesque setup is representative of the norm, what good does presenting it really do in terms of contradicting anything I've said?
Kindly accept that most people do have preferences of some kind. Maybe there are some guys who own an Xbox 360 but would rather wait for GoW2 to be ported to PC, but they're a negligible bunch. And they're windmill-tilters to boot, because no PC port for GoW2 is forthcoming--it's exclusive even by your standards. But if there was a port in coming in six more months, the 360 owners are by and large not going to wait, and that's borne out by how badly the PC port of GoW1 sold.
