Now they're selling PS2 Classics on PSN and busting out a bunch of HD remakes at retail. It's a safe assumption that, if PS2 discs worked on PS3, gamers would be more likely to ignore these releases. Why pay $40 for something you already own? I fully expect them to do a similar thing with PS4.
Nintendo is a good example of a company that at least tries to east their customers into the next system. The Wii played GameCube discs even though they were an odd shape, not to mention they went out of their way to include GC controller and memory card slots too. With the original DS, they added a GameBoy Advance port. In contrast to that, the Vita doesn't support PSP games and uses completely different (and unique to the Vita) memory cards.
I'm not trying to vilify Sony or anything, they can do what they like, but I'm not sure their excuse is completely honest. That being said, I admittedly don't know much about the technical side of things (as far as the Cell processor and how expensive/complicated it is) but I do know that if they really cared, they would have figured out a solution.
