Quoted from mbaumle:If this does come to fruition, I think they missed out on the Harry Potter hype by like 5 or more years if they wanted to appeal to the casual crowd, but with the Cursed Child being in theaters, there has been a resurgence in popularity.

Yes and no. The original child readers of the HP books are now in their 30's (books started in 1997). This would be a good time to sell pins to them.
