If I read their Facebook page correctly it seems that the Panzer IVs and the Stugs at least are all new toolings, and represent something of a change of approach in that they appear to have one piece track and wheel units, like the Trumpeter Dicker Max and the Airfix Cromwell. I don't necessarily disdain that idea but it will depend of course on how well it is executed. A slightly worrying CAD image does seem to suggest that the backs of the wheels will be devoid of detail, and that both halves of the wheels are moulded together; detail wise it would make more sense to mould the wheel backs in place with detail on that face, then add the wheel outers separately. It seems however that they are determined to cut out any need for laborious wheel clean up and make things "easy".
I noticed in one shot that there was spare track link on the front plate, something that Dragon have conspicuously omitted in the past, but whether it is moulded in place or separate I don't know. It does look as if tools are probably moulded on. As has been pointed out before, some of their approach may be related to using some of the same parts in their ready built "collectors" models which are probably assembled on a production line.
No matter really though if that's what they want to do and can make money from it, there are other interesting manufacturers who are now upping the braille scale standard.
