Per Destructoid/Sony comments PSN purchases won't be moved over to PS4.The only backwards compatibility I really care about is if I had bought something like say Limbo, on PSN. Then, if it shows up on the PS4 Store, I'd want my account flagged as owning it and able to d/l it. So, direct ports of the same game to ps4? Yes. All the other stuff? Their future gaikai solution seems fine by me.
