Unless there is alot of evidence that the LoS sequel is heading in a better direction from my point of view (more memorable and varied music, less Lord of the Rings feel and steered more toward traditional CV gothic dark fiction, etc.), I will more than likely be holding off on buying it. I'll be watching the sequel more intently and will more than likely be putting it under alot of scrutiny due to Lords not exactly being what I was hoping for.
I'm not saying I'll never buy the game if I don't feel it's grown more into its Castlevania roots, as I am a collector of the series and have a tic about making my collection more complete, but I'll probably wait until long after the game has dropped price as I don't want Konami getting my top dollar for a game I don't approve of.
