I believe so. I was just at Nintendo World Store and asked the same thing. The guy said that they were planning it, so if his information is correct, then yes.Juniors is 12 and under. I remember the pokemon showdown and i was 13 and i was the youngest in the senior division. Something i noticed is that they dont check your age. Some juniors can apply for both the Junior and Senior Division and which ever they get in they can either be a year older or younger. I was very suprised to see how many older kids and adults played.
EDIT: Does anyone know if pokemon is going to have an early release for HG/SS at rockafeller center again?
They always do these kinds of releases anyways. I'd be surprised if they didn't.
