Yeah, PS3 disc based games eventually will play through the PS4, with PSN games arriving first (easier to port).
With Sonys acquisition of Gaikai two years back, they paved the way for it to happen. I am hopeful that Sony may allow registration of disc based PS3 games we already own on this service to allow streaming access at no cost.
That said, I recognise that Sony have never been that generous before. I for one, will ensure I have a boxed PS3 ready to go, just in case.
There's no doubt that PS1, Ps2 and PS3 games will be available, Sony recognise the potential sales aspect in not only providing access to originals but also HD re-releases.
