I don't think so crisis. Then again, I thought that ending was only an urban legend.
No, I think the bad ending he is referring to is the one in which you don't get the holy glasses and just simply kill Richter. Which ends with the castle crumbling and Alucard standing on a ledge saying "farewell land of my birth".
What would happen? Would Alucard disappear while Dracula conquers the world? What would happen to Shaft? Would a new hero defeat Dracula? I just want to see what you guys can come up with.
Well, assuming that Shaft is still around, he would likely continue to resurrect Dracula and if a new hero didn't come along, Alucard would likely awaken again and fight. After all, what is it that originally woke up Alucard in the first place? I think that it was the shift in the balance of power between good and evil. So, following that logic, unless there is a powerful force of good keeping up the good fight, Alucard will wake up to stop the evil.
