The 360 has no exclusives according to most PS3 fans
I think that's probably an extreme generalization. The PS3 seems to have well more exclusives released taking equal timeframes as well as with regard to the current known line-up for 2009 and 2010. But that's something else.
You are probably referring to very few anonymous posters. For example don't you consider me a PS3 fan? My take here at VGChartz:
"Regarding exclusives, you need to look at who the publisher is. If the game is published by Microsoft it's likely to stay exclusive for the 360 and those published worldwide by Sony will stay exclusive to the PS3.
Regarding 3rd parties, they are usually multi-platform developers. Thus all the once exclusive best sold 360 games which aren't too old have so far been ported to the PS3 (only exception may be Valve games, as that company is run by an ex Microsoft employee)
Vice versa that's also the case, but a few games may not be ported to the 360 mainly due to technical reasons such as with regard to Metal Gear Solid 4."
