According to the ESRB and the Australian Classification board, classic SNK titles will be coming to the PlayStation Network, and playable on both the PS3 and PSP.

Alpha Mission II, Baseball Stars Professional, League Bowling and Super Sidekicks have all been rated on the ESRB for both systems. This appears to be based on the same sort of deal that PSOne Classics and the Japanese Turbografx titles are based on - strictly emulated titles to download on both systems.

Based on the initial lineup, the pickings seem to be pretty small. Games like the King of Fighters and games that have already appeared on the Xbox Live Arcade. In fact, all these titles have not been on the Nintendo Virtual Console either, so it seems that there are a lot of exclusitivity involved with SNK titles on digital platforms at the moment.

We should get an official update soon, hopefully with a list of upcoming titles.
