I think they will take a break when the anime is back up. Seems atm that anime got break so I believe simple that manga gets break after when the anime workers are back.
Shonen Jump is gonna be on a 2 week break, and possibly there will be no manga.
And a couple of times the manga didnt have a delay printed on it, but still skipped a week
I looked at past chapters where there has been a break after that last manga chapter in December and none of them had an indication of a break on the last page. There will be a magazine published on the 4th, and whether or not Naruto will be in it I haven't been able to determine.
