I love a solid Castlevania game, but from the sound of things it looks like Konami isn't looking to allow the series to evolve any time soon. Consider this quote from Castlevania development maven Koji Igarashi regarding possibly bringing the popular franchise to Nintendo's new Wii:
Castlevania producer Koji Igarashi said that Castlevania does not fit with Wii, because the Wii market is for people who want to have new experience, these type of people do not have time to play lengthy games like Castlevania; also he does not have a good idea to make use of the Wii controller in the game.
Did you catch that? The Wii is for people who want new experiences, and since Castlevania isn't Wii material, the conclusion is that Castlevania won't be changing in the next generation of video games. While the 2D handheld installments get better with each sequel (Dawn of Sorrow was the most fun I've had with a Castlevania title since the original NES game and the upcoming Portrait of Ruin is looking even better), the 3D home console versions need a bit of a pick-me-up. What better than to infuse it with the new creative blood flowing through the Wii? As Kotaku suggests, just image plunging the Wii's freehand controller through the heart of a vampire like a stake. I could get behind that. It's too bad that Konami is not willing to do the same.
