The proliferation of acts from Hybe itself appears to be the cause that there will not be any clear cut front runner among the 4th Gen of KPoppers.
The reason is Hybe won't really want a clear front runner but will want to compete its acts against each other, like these AKB and -zaka acts in Japan competing against each other.
Which means, unlike the old days where there was just one, or at most two, front runners leading KPop and everyone else following, there will not be a clear winner. Unlike SM, which pushed TVXQ and suppressed Super Junior and Shinee, pushed EXO and suppressed Red Velvet and so forth, Hybe will let Act A win Grand Prize this year, Act B next year, and so on. For Mr. Bang, every act he owns is kinda the same, and other that BTS which he developed himself, he will probably treat his other acts with some degree of equality.
That means it won't be very likely for an act to completely dominate a generation since other acts will take that into advantage and continue to carve their niches.
