Seems like Shonen Jump will be available on Monday, 29th of December. MH confirmed it and there are already Naruto spoiler confirmed.
Hope this thread is helpfull
Although there are confirmed spoilers of many series, it seems it will not go on sale this week.
It's pretty mixed up because we've gone back and forth whether there is not. Latest news are that the next sale is January 5 for Japan, which means we'll get it around January 2 or 3.
