Status of Z-Axis/PRO Electronics for Crossfire XL

Any updates on lead time to the Z-Axix/PRO Electronics Box being available for the Crossfire XL model?

I read the statement that “after all batch 1 and batch 2 Crossfire PRO machines are delivered, we will offer the Z axis kit…”

So when is the batch 1 & 2 ordered expected to be complete?
