@Yatsuki Yeah I sure hope so !
From what we know, when the attack happened, Vergil was playing outside so he was obviously the first one to get attacked.
=> What I especially want to know is why Vergil got Yamato in the first place !? We may have gotten "some clarification" for Dante but not for Vergil.
And Yamato was a special case among Sparda's weapons... That devil arm was quite vital if you take its "dimensional slash" and "Underworld sealing" abilities so I wouldn't be surprised if the demons tried to retrieve it on the same night they attacked the twins' home.
