I'm somewhat amused that the source for a piece of news for a Nintendo World Report news story is...the official PlayStation blog.

It's a bit weird that Rondo of Blood isn't in this collection since the intent was clearly to put together one type of Castlevania game. Yeah, it's part of another recent re-release, but still. I suppose if we get a 2nd collection with the Symphony-style of games, it would make sense to be there as well since it ties into Symphony.
As for the game selection, this is a damn good list. It's nice to finally have Bloodlines re-released.
