In ten years, there will be a lot more different federations running their own competitions with their own rules.
so you will the creation of different branches of BJJ.
of course you still see the branches of the original GJJ.
there will be lot more BB teaching so the prices of your average BJJ clubs will be the same as Judo while still having the expensive club run by world champions.
MMA will be a sport of its own and will become massive.
Each countries will start developing their own style of Jiu Jitsu. like the French and Russians are known to haver their own style of Judo.
As long as commentators in UFC keep using the word Jiu Jitsu and terminology, it is free advertising for BJJ clubs but consumers will become more savy and might be attracted towards mma clubs instead of a BJJ club.
Basically, if you think to get your BB in BJJ and become as rich as your current BJJ instructor, I do not think it is gonna be the case in 10 years time.
