We have received a small shop update a while back where we had a Deidara added to the Group Shop and Itachi added to Arena Shop.
This is only 2 out of 4 shops that I thought will be updated at the same time.
Considering it's been more than 2 weeks since half of the shop was updated I'd like to propose that both Ranked and Survival shops receive an update in form of a recruitable Ninja just like the other two.
I've a pile of both ranked and survival points stacking up without any viable item to be spent on.
