I love the 2D side scrolling CastleVania games. I'm a big fan of the older games. Like CV1, 2, 3 and 4. I'd like to see a new game with Stage by stage, something like CVIII, but with todays DS graphics. But with new spries. I don't really like that they use the 1993 Chi no Rondo sprites even today... It's pretty amazing that they use sprites made 15 years ago... Why don't Square-enix reuse thier sprites from Final Fantasy VI xD But anyway... I know why they re used most of the sprites in DoS, that was couse a tight deadline, so they just too the enemys fron SotN couse they did'nt have time to make new ones... I really hope they make new, forexapmle skeleton sprites... I've seen those in the games for a bit too long now. I am kinda spriter so I know that it can take time making a sprite sheet, and for a whole game with 100th of sprites that will take sometime. I hope they make alot of new sprites and enemys and even new bosses in the next CV game.
and by the way... CastleVania is better than Metroid
