I seem to remember a while back, a documented interview with IGA of him saying his plans to create a sequel to Symphony on a next-gen platform (which, obviously, is what that TGS teaser was). I'll do some searching & see if I could post the link.
But yeah, CotM stated Morris Baldwin defeated Dracula 10 years prior. Also, Hugh seems to put some significance to Nathan's whip, despite it not being the VK. Those tidbits right there are left field. And it was an Austrian castle(??)
Maybe the guys that made it intended to make a prequel at some point.
If thats the case then information like that would be appreciated. I do hope that game gets released some time though I dont see how with LoS coming out. Though I recall an interview with Cox (I think) and they asked him if there was going to be another Castlevania on the DSi he stated he had no comment and I think he also stated he couldn't comment on whether or not IGA was working on another Castlevania game. IGA has also been reported in working on a new project so who knows.
Could be probably they intended to do a prequel but with IGA taking the reigns they obviously didn't get to do that. We were discussing that in the Sorrow Novel (released in japan) Curtis, who is being trained by Julius after the evens of DoS, is weilding a "Holy Whip" the Hunter whip would just be an offshoot of the Vampire Killer much like like this Holy Whip.
EDIT Also adding in Simon's Quest you obtain different whips so introducing a new whip isn't anything new or left field and neither is the Castle in Austria being in Bloodlines you traveled all over Europe and in Simons Quest you went to different Castles so that really isn't anything left field either nor is the 10 years prior thing being that in the 64 games Cornell defeated Dracula in LoD 8 years prior to Castlevania 64. In both cases he was prematurely resurrected to try and regain his full power. Also in Simon's Quest he placed a curse on Simon so he would have to bring him back and in Adventure though he technically didn't die he still returned 15 years later. I'm sorry but all those cases really aren't left field or out of the ordinary for Castlevania. Now had they introduced a totally different background story for Dracula, changed the whips name from VK to Hunter's Whip and made replaced the Belmonts with the Graves and made it all take place in Austria instead of Translyvania and saying that this has been going on for hundreds of years then yeah I would say left field.
I think that Dracula's follows kinda figured out that they could just resurrect their master "Hey you know what screw that hundred year thing I mean we got necromancy, devil forgemaster,
apple juice, alchemy, sorcery, and all kinds of other mad skillz lets just bring him back to life." With 1999 approaching I can see why they would be scampering to bring him back.
