There's logical reasons for the splicers to go to Venus. That's where the vault of glass & other vex technology is located. Plus another fallen house has been there since vanilla, so the splicers could go there for whatever attracted the other house in the 1st place, maybe even as an attempt to unite the two houses like Skolas tried to do in HoW. I'm not interested in the rehashed vs. new content debate. Bungie is gonna do what they want, & lore isn't gonna affect the choice they make. I just thought the topics of SIVA being on Venus & a rehashed Nexus being canonical was interesting.
