Every youtuber that did minecraft? You mean people like Captainsparklez, SSundee, DanTDM and all those?
anyway, I'm sure its going to become less. I'm also sure its going to hang on by the fingernails for more than 4 years. I won't be in this community in 4 years. But I expect to see a whole bunch of new players. Possibly a fully overhauled minecraft 2.0.
With the data you have available, your expectations are correct. It would however be completely unrealistic as well as foolish to assume that these data will not change in the meantime.
Fortunately, the community will not require any people who "hang on for the sake of hanging on".
I've illustrated why Minecraft is not dying in my latest reply and I'd appreciate it if you could read it.
