All of the above is speculatative, as I don't know them personally. I have just asked around and this is the story I have been told. Take it for what ever internet gossip is worth.

Dear Andy,
Thanks for your e-mail. Yes, we have spoken to each other in the past. I am glad to get in touch with you again.
We are pleased to hear that you like Sherman. We have developed 16 versions of Sherman already and upgrade kits. We will release them each period of time.
We are also considering to develop other products like which you said. Thanks for the information for us.
I will contact with you again once the Sherman is ready.
Best regards,
Janey
