In the picture above, I notice that it is all First Order stuff. I don't mind the Sequels, personally. But I think everyone would like to see more from the OT and possibly, the PT. Definitely the Mandalorian.
These are all deeply discounted kits, but on the shelf right above it is the Sandtrooper kit at full price
I think a big part of the problem is Disney wanted Bandai to produce stuff for the sequels, but apparently it did not sell yet they were still contracted to do so for the next few movies
It's one of the reasons they probably went for slight re-tools of Force Awakens kits (like the different colored X-Wings, the Falcon with new dish, etc... over wasting time on some of the other kits like Kylo Ren's Tie Fighter or the ties from Rise of Skywalker.
I am guessing based on lackluster demand for Force Awakens kits they did whatever bare minimum they had to in order to fulfill demands by Disney for new product while slipping in some OT kits.
Remember, they need approval from the license holder to produce kits. If Disney wants a First Order Tie Fighter that is going to take precedence over a Tie Bomber for example.
While I cannot confirm so, I seem to remember reading somewhere that Lucas still gets a merchandising cut of the pre-Disney stuff which could be why they are reluctant to dip too much into that era as well
And as I was told, the division that handles the SH Figuart figures and key chain logs and stuff is a different division than the modeling division which is now known as Bandai Spirits. So just because they may be releasing Mandalorian stuff in the SH Figuart line does not mean they have a current license for the model division.
At the very least, the hope we can hold on to is they still seem to be repopping the better selling kits periodically. Hopefully we see something new, but for now, there is nothin on the release schedule
