Well, i don't think the tent pole theatrical events are what they once were. In the older days Hasbro used the Movie years to bankroll the in between years, which allowed them to make some of the VG/EU etc Characters that didn't coincide with the movie. The line's popularity back then gave them the ability to make certain fringe characters once in a great while. I also feel that repacks no longer bring in the revenue they once did, because we see less of them and new figure on the whole.
I think the biggest problem with Disney being in charge, is that we may never see some of those figures that might have been possible prior to. Because they want to push "their" Star Wars character whether they such or not. And will do so even if they don't become popular.
Even before Disney took over Hasbro was reluctant to do EU characters due to them being "unknowns" to the larger audience. "kids" However, they did start to improve in later years, then Disney happened right when it was getting good. These days even Kids don't seem to be that interested, especially when Hasbro cancels the 5POA line. You know the one they had previously said was doing "great"? Okay "hiatus" whatever.
When TVC goes on hiatus it's one thing, but when the cheaper affordable line goes away. What does this tell us? Things aren't so great anymore.
Even though there will be a gap without Movies, there will be those Disney+ shows, that I assume will get figures too. Just like past TV media. So there shouldn't be a "darktimes" like it was after 85.
I think the only hope we haver for seeing some of our favorite EU characters in figure form, would be too see them used in the current media. And even then it's not a guarantee.
