I wouldn't mind them ending the story. Eventually, it has to end. There's just so many things they could do with the still-unfinished original timeline it would be a shame to begin a periodical rebooting. Hell, I think it would be unfortunate even after the continuity was fulfilled. I like it when Richter recognizes Al in SotN as his ancestor's ally. And even at the risk of sounding silly, I even like it when in Judgment Drac refers to the battles he had with all his enemies over the years. I especially like it when he flat out tells Simon his curse is going to kill him.
Actually, that's one of the several reasons I like SotN; unlike other CVs, it referenced past events directly. I loved seeing the connection between DC, Rondo and SotN and I was waiting forward to what Al and Drac would talk about before their inevitable duel.
Belmonts are a dynasty and Dracula is eternal. That's a setting that can span several different canons. But I would not like if it was a cycle of pushing the reset button after every three or so games.
