Brock will not going to a new Pokémon journey with Ash after Sinnoh League will be over. True or False?

I pick choice A, I think that this is true because Brock has tagged along on too many adventures with Ash and he may get tired of tagging along with Ash.

Or he may leave due to the same exact reason that Misty stopped following Ash(he may become a gym leader again)

Or, he might leave due to the same reason that Gary Oak stopped being Ash's rival(he might pursue his Pokemon Breeder Dream further without Ash)

Or he might stop following Ash because he finally meets his love match and true soulmate.

We can only hope for A.
