As many problems as I had with season 3 of The Mandalorian, I give credit to the writers of the show that they didn't change Mando's look at all this season. Zero changes. They would sell a LOT more merchandise if his armor changed, especially drastically, during the season, but they didn't force that in just for that (or any other) motivation.
I'm sure Hot Toys will be able to put together a season 3 version that is SLIGHTLY different than this one (no spoilers here), but it will be very minimal changes.
