The Deacon - will it change, and by how much when we see it next?

I think this is a cert to happen as we've seen with every other xeno type when it is born, even up to Cuddles. Original Xeno - chestburster to full xeno was a BIG change in a short time - some resemblance in the head. Cuddles - the squid like form with its main egg like body, changed into the huge proto-hugger that however had NO SIGN of the body it was originally born with - another pause for thought there. I'm sure there are other examples along the way than these iconic ones... But my point is, will we see a notable change in the Proto that was born from the Engineer in it's newborn state essentially? Will it grow as the examples we have seen before?
