Wait, I figured that Resurrection was set BEFORE the modern times scenario. I read it wrong, then, as many of these sites are saying it's set after the final ending scene, not leading to events that eventually get there. It's in fact set after Dracula goes poof in that final scene? Wow, that's surprising, if true. I was assuming they'd leave that scenario for a sequel...
Sites can't seem to make up their minds if it's after the ending or the epilogue, which lead to two different assumptions, so I guess we'll have to wait for a more solid stamp. At least we know that there will be two pieces of Castlevania content surely coming out next year.
