Those posts complaining about Part 5 when??? are funny as a meme and all but at the same time kind of a mess? Vento Aureo’s going to happen
but was never going to get announced before now. After the Jojofes,
live-action and Rohan OVA hype - Part 5 would have stepped all over that
- but before the end of the year since 2017’s 30 Years of Jojo. fwiw Jump Festa 2018 is in 2017 (mid-December)
so I’d expect it by then. imo.
