8ch may be back but its never gonna go back to being a hub for user-created boards, it'll just be a place for qanon conspiracy, even moreso than 8chan ever was. It may as well be called qchan. Other boards may exist but they'll be more or less ignored by the wider userbase, people flocking to 8kun after hearing about how it got taken down by cloudflare.
Watkins says he thinks 8kun will be more popular than 8chan but I can't see that actually happening unless he actually means by the stormfront community.
Its a shame really, a website where people can form imageboard communities under whatever subject has a potential to be great but I don't think 8kun will do any better than 8chan was doing when they were shut down.
