When my airbrush died, and it's replacement was backordered a few months back, I happily discovered World of Tanks, something to feed my panzer addiction until my modeling could resume. Well, after 2300 plus battles and an amazing amount of fun, I see a possibility that this will benefit armor modelers, whether they play the game or not.
I am amazed at the hordes of people playing, talking about things like the merit of the 88mm L71, or the Russion proclivity for massive heavies. There are thousands of people becoming interested and acquainted with the armor in the game, and I'm betting that many have never thought about modeling. I know of several, who through playing the game, have the urge to build what they are fighting with or against.
The game also has many cool / obscure types that are not in kit form yet, but this interest may create the demand for them.
My sons (who live out of state) and I routinely form a platoon and fight together. It's a blast, and their interst in my collection has been sparked, especialy when something they have in their "garage" has either already been built, or is avalable to be built,
To give you some idea of the range of units, my "garage" currently includes; Soviet - BT7, SU5, SU-85; German: Pzr 38nA, Stug III, Leopard, Hetzer, Grille, Hummel, VK 3601, Panther and Tiger. Many, many more. Some are "paper panzers", especially American heavies, etc. There are 5 main categories; 1) Light Tanks, 2)Medium Tanks, 3) Heavy Tanks, 4) Tank Destroyers, 5)SPG (arty).
Whether you like the game or not, there are enough who do to make me optimistic about positive impact on armor modeling.
