Gradius Collection got released on EU PSN. That was a bit of a stealth release! (came out on the 4th of June). I remember Silent Hill being announced but not that. Doesn't say Vita compatible, but Silent Hill doesn't either and I'm sure you can get that on Vita.
I wonder if CastleVania: Dracula X Chronicles might come to PSN soon then as it seems Konami are slowly filling out gaps in the back catalogue.
