I've wanted to get original copies of the GB Castlevanias, but I've wondered if I should wait and see if I can find the European colorized versions (Konami GB Collection, Vol. 1 and 4). Unfortunately the last EU copy of 4 I saw on ebay was like $60 loose (not as interested in the Japanese, since those aren't GBC). If that's really what they go for, I'll guess I'll have to pass and get a standard cart instead.
Though it's likely Konami will put the originals on 3DS VC.

Bloodlines (love hearing the Genesis version of Vampire Killer and tempted to buy a Genesis just to play this game) and Dracula X

ok i downloaded Rondo Of Blood just now, i hope it convinces Konami just that much more to release Bloodlines.
both of these games are epic imo

I just hope Konami comes back to releasing Virtual Console games on the Wii or the 3DS. Doesn't have to be Castlevania anymore.

Come back Konami, all is forgiven!

I'll concur with the Kid Dracula nomination, it'd be really cool if the Famicom version was made available as an import title. They'd have to at least translate the Statue of Liberty quiz, but it looks like such an incredibly fun game.
