So its basically a way to wait until enough Jumps have been send to stores to no get caught, i know that copyright laws in Japan are quite hard and can really get u arrested.
About redon, dont think the man is in Japan to get arrested, most likely he got info from some sources and just want to protect them by not leaking the info too early. Wouldnt be soo difficult to find a spanish man in Japan lol.
And of course he dont do that for the spotlight, basically everyone in the community already know him lol.
Heard some years ago that the Jump is sold in other places in East Asia like Korea, Taiwan, HK and Singapore, and the leaks came from those places.
