I recently got myself a PS Vita, and before going away for 10 days I bought "Castlevania: Dracula X Chronicles" for it, which is a remake of "Castlevania: Rondo of Blood" for the PSP, which also contains an unlockable port of "Castlevania: Symphony of the Night".
Not being an experienced Castlevania player, I don't know whether there's shame to admit it, but here goes: "Rondo of Blood" is really kicking my ass right now. For some reason, level 3 gives me a lot of trouble, and the one time I managed to complete it, I forgot to save.
So, yeah, I'm playing this at the moment.
