I'm finding the opposite. In fact, I have no problem finding Luke and Rey from the 3.75" line either. And it doesn't hurt that the Rey/Praetorian Guard 2-pack is plentiful as well, so any kid looking to get Rey from the new movie shouldn't be having any problem at all. So from an optics stand-point - Hasbro did something RIGHT for once.
The only figure that I don't see much of anymore is Paige - and that's probably due to the fact that in the later cases of the Teal assortment she's been dropped to make room for Obi-Wan and Yoda - both of whom I'm seeing more and more of.
