There will be a closed beta later this month with the service rolling out this summer(in North America). The service will use GaiKai to stream ps1,ps2, and ps3 games directly to you PS4, PS3, Ps Vita, Sony brand TVs, and various tablets and smartphones.
Prices have not been set but at the moment it is know you can rent games individually or pay a subscription fee(it's unknown if this will included with Playstation plus or whether you'll have to pay extra) and it's not know how this will be effected if you purchased these games previously on the playstation store. The last of us and Beyond: Two Souls will be at launch since they will be playable on the CES floor via bravia tvs and ps vitas.
