Hi! thanks for your interest in the helmet, we have full intention to continue to work on him more. Sadly we've not had any communication with DE on any changes, so have been unable to do anything with him. Any changes we would make would be a guess on what they might see fit.
we're patiently waiting.

So i guess the answer is sadly No, the helmet is sadly not being developed further (for now)

Ok, that's what I was figuring was the case, then. Hopefully having "no notes" is a good sign that it doesn't need any further improvements and is ready for the game!
