Of course the series will continue. I won't let them stop until I see a Belmont in one of them!!! Go Richter Belmont!
Getting Dracula X Chronicles soon... I haven't even played Rondo of Blood and I'm already a Richter Belmont fan. Love Castlevania as a whole, though. I got Brawl recently, and I think Castlevania could work soooo well with SSB...
