I think it has already been said somewhere in the thread, but...
The level of detail in the new tank system is WAY beyond anything we have done before. Actually, it is WAY beyond anything ANYONE has done before, as far as I know.
Remember - you are getting a full 3D interior to the vehicle. Including all the crew. All animated and functioning. You saw the loader in the trailer...
You are also getting all the ammo bins, all the fuel cells, the transmission, drive shaft, optics, etc etc.
The exterior models took something like 6 man-weeks of work, the interior about 3 man-months for one tank. It may be less going forward, now Rob has worked out most of the tricks - but it is still a heavy job.
I think you have as much systems functionality in Steel Beasts, but without the interior model and crew. WWII Online probably has similar mechanics, but based on much more dated research and also missing the interior modeling.
So - only 2 vehicles at launch... it is a LOT of work
