Joke? The original PS3's had hardware based BC and then after PS3's had software based BC. Then they took that away, leaving nothing.
EDIT: Apologies if I'm missing something here.
PS3's "software" emulation of the PS2 was semi-hardware based (80GB models only software emulated the EE (CPU/VUs) of the PS2, it still had the graphics hardware soldered to the mother board).
The current implementation of emulation is very limited, requiring a lot of hand coded optimizations per game and being limited as to what games will work with it (which is why you can't just shove a PS2 disc into the system and play, the compatibility is so low, and the effort they have to put into optimization is why they sell them via the store).
As for emulating the PS3 on the PS4? Completely 100% out of the question, will never happen. Bookmark this post, bring it up in a few years to make me eat crow if you like, but emulation of the PS3 on the PS4 won't happen.
