Feast your eyes on 2014s Jump Issue covers.... the last cover being some pink girl thing
So many new faces..... they all died at such a young age
For 'fun' here's how many times a series appeared on the cover this year on Jump (only counting a series if they are the main one, not with a bunch of other series):
A bunch of series: 7
Assassinate Classroom: 4
Kuroko: 3
Naruto: 3
World Trigger: 3
Gintama: 2
Toriko: 2
Sum: 2
One Piece: 2
Soma: 2
The rest of these are one time covers (mostly during their debut chapter):
Iron Knight, Illegal Rare, iShoujo, Stealth Symphony, Tokyo Wonder Boys, Haikyuu, Nisekoi, Saiki Kusuo no Psi-nan, My Hero Academia, Mitsukubi Condor, Yoakemono, Bleach, Judos, Hi-Fi Cluster, Sporting Salt, Kochikame, Takujō no Ageha, E-Robot
According to Wiki, here's the 2014 series:
Iron Knight (quick death)
Illegal Rare (sort of quick death)
iShojo (quick death)
Stealth Symphony (quick death)
Tokyo Wonder Boys (VERY quick death)
Hinomaru Sumo (still going strong)
My Hero Academia (still going VERY strong)
Mitsukubi Condor (quick death)
Yoakemono (quick death)
Judos (may last a little longer)
Hi-Fi Cluster (dead series walking)
Sporting Salt (dead series walking)
Takujō no Ageha (too soon to tell)
E-Robot (too soon to tell... but it will probably die)
The first series of 2015 will be Gakkyū Hōtei
So basically half of the new series in Jump have already been cancelled. And we have basically 2-3 more that'll probably be cancelled early next year too.
