Predictions on Growth of New Series (2014-2016)
Hinomaru Zumou: If it gets an adaptation that isn't rushed, and well-animated, could see this growing to 100-150 or even 200k.
My Hero Academia: If the 2nd season boosts it more, 500-600 or even 700k, although that's really pushing it.
Black Clover: Well-animated and not rushed with good pacing, 400-500k. It could grow more though, if the fujoshi audience supports it a bit.
Sesuji wo Pin! - Well-animated + not rushed, 200-300k and I think Bones or KyoAni or another studio that does SOL well could boost it a lot. Since the recent tournament arc hurt it a lot in rankings, it's finally rising again, which gives me hope for the series to keep surviving.
Samon the Summoner - Directed by Fujita w/well-known seiyuu, around as much as Gintama. Fujoshi audience could help this get a big boost.
Yuragi-sou no Yuuna-san - If its sales keep increasing at this rate, and the future has good animation/no rushed pacing or a well-known studio behind it with well-known seiyuu, easily could boost to TLRD levels of success, possibly up to Nisekoi levels.
Kimetsu no Yaiba - Good pacing / animation and fujoshi audience could boost it up to World Trigger levels of success (250-300k)
Neverland - If pacing is done well, could bring it up to 400k or even more. That is, if the series keeps surviving the Jump environment.
If this 2nd season of MHA does not boost it anymore, then I can't see it rising in sales much more unless something unexpected happens.
Rushed adaptations tend to fail in Japan, as seen with S2 of Shokugeki and other anime with fast pacing.
