Well, I suppose they could get away with it. Backwards compatibility is such a mess with the PS3... some work 100%, some are extremely hit & miss, and others just don't work at all. But I'm sure they make a huge profit off of every new PS2 sold... this is Sony we're talking about, they wouldn't give up that revenue stream.
