Didnt play PD0, no interest (felt it was a game that was pushed only because it was slim pickins at launch). I'll pass on this title as well. I mean come on....the hole on the wall was bigger than a door, I couldn't even push forward and have the guy plow through the reamining debris?!?! A non-immersive FPS is not in the cards for me.
We really can't try to find patterns in the BC list because we haven't had enough updates to go on. Tony Hawk's American Waste(land) is BC, and it is a title for the 360, so I would say that it isn't always true that native titles aren't getting BC to boost sales for the native 360 version. I agree newer games should be BC, and I don't have an example either way, but Burnout Revenege was released in mid-September, two months from launch - being one of the most popular franchises available you would think MS would force BC with games that close to launch. Of course, maybe the renderware engine is harder to port....who knows.
I wouldn't count on it being BC out of the box, i would hope for a new BC update wih support.
