I'm not sold on this, tbh. The English market is limited. So is the number of talents actually worth something, judging by the constant reincarnations. Only rarely do we see genuinely new blood being injected.
I'm not sold on people with deep pockets being all that interested unless their investment can genuinely compete for the top.
Basically all EN startups were launched by incompetent enthusiasts that didn't know what they were doing. A few (Fishman, Gunrun, maybe Aviel) were less incompetent than others and ended up on top. But I think the "Enthusiasts" part is pretty telling. Either they're massive idolfags (Fishman) or they have a streaming background (Gunrun, Aviel).
Vtubing is attracting big money in the much larger Japanese market. In the west, eh... People joke about Aviel's shekels, but it's hardly that much, just a bit of clever advertising. Gunrun got an eleven million injection, but eleven million are a pretty paltry sum in the entertainment industry.
I don't see this situation changing anytime soon. That doesn't mean that the corpo ranks will remain static, but I believe that whatever changes happen are much more likely to be the result of Niji style fuckups than of spontaneous big money injections.
Hell. We have seen what big investors trying out vtubing looks like. Remember Vee Project by Sony?
Yeah, me neither. I had to look it up.
