Anyone clear this up for me?

The article says it has "some" BC, how can youdetermine which games are /are not compatible? 

95% BC .......sony has the list on their official site

It's the 80g bundle isn't it. So it'll have the same list of games that work for it as the rest of the 80g. I think Sony has it posted somewhere.

You can try this link,

http://www.us.playstation.com/Support/CompatibleStatus

It says 'some BC' because some of the hardware (the PS2 GPU?) was removed in the 80gig unit and is now emulated through software as opposed to the earlier 60gig and 20gig PS3's which sport full hardware backwards compatibility.

Thanks Paladin. That makes sense, since I knew they weren't adding the emotion chip back in. So it's NOT the same 80 GB that launched a while back.
