I noticed something when going through German techtree and checking those modules:
Maus, G.W. E 100, E-100, JagdPz E-100, E-50 Ausf. M, VK 72.01 (K)
So, VK 72.01 (K). Is this the Failöwe which will probably be a reward for a CW campaign in the future?
I don't know, so please, discuss.
EDIT: when I tried to edit this post, the "editor" removed the space between the lines which makes it look stupid, but I guess you can still get the point.
