Because when they say hes dead it means hes dead. Its not like how Vergil was in DMC1 with them saying he appeared to have vanished or capcom would simply say he was defeated and never gave a flat out answer on his position until DMC4 came out then they announced he was dead(well they announced Nelo to be dead and not Vergil but they are both the same person so...). But with Sparda they have been saying this the whole time. Also yes i do want Sparda dead for the simple fact legends like him should never reappear once they are dubbed as dead for such a long time its no point in bringing him back he did his duty now Dante will take his place and Dante's son after that or w/e so on and so on. Hes been saving the world for like what? 2000 years, yeah let him rest. Now on Vergil i wouldn't care if he returned or not but he is dead for sure. He died twice actually. Mundus killed(so they say) and turned his demonic soul inside out thus making Nelo Angelo. Then Dante defeated this creature and this time he died for sure as Kobayashi saying he exploded into pieces leaving behind the Amulet to defeat Mundus. Now i don't know how he will return but they have to plan it smart but surely he will. But i don't see the point in bringing him back other then a playable character because his motivation in 3 was too strong to let go that easily he had no regard for human life after his mother was killed. This will lead to him losing again to Dante. I mean if this was a anime then i would like for Sparda to come back but this is a video game and they only make them once every 2 or 3 years and thats too long.
