Considering Silver Spoon was a 1 million seller for a time, hard to imagine a manga raising it even higher, but it would be interesting to see Jump trying something.
I know Silver Spoon was a million seller, but there's a niche sport that's in Sunday, (even then, the Equestrian aspect wasn't even a big part of the story) and there's a niche sport that's in JUMP. Besides Silver Spoon's main selling point is the comedy.
Also, here's my predictions:
*Stephen A. Smith Voice*
-One Piece slides down in sales from previous year, only nearly reaching #1 by a thin margin,
-Galaxy Gangs is not getting published.
-Komi comes back with a battle/adventure manga
-Tosh, same as above
-Erica gets serialized along with a badminton manga (maybe even have the duo based on Susi & Alan)
-Kimetsu maintains dominance once again.
-MHA will get another anime in October
-KImetsu vs One Piece discrepancy will blow up and Nakano gets fired.
