What I don't understand is why we're getting so many new designs, new concepts that were never seen in the OT when this is set right before the OT begins...
That being said - I think the minifigure list at the bottom of that post is just the unique figures, there will undoubtedly be multiples of the troopers in each of these sets. Look at the floating tank set - the main picture shows two troopers but the minifigure chart only shows two. I would be VERY shocked if we didn't get Rogue One themed Rebels and Empire battle packs in 2017 to even further bolster the trooper figures.
The set I'm looking forward to seeing the most is the new Death Star set.
