Yeah sucks to wait, why I strongly recommend any Zion waiters jump in on the Milaana today while they still can. It can tide you over until Zion comes, and would be a very nice back up if nothing else, without the portability needs and such it is still a great vape all on its own, would be good to have if Zion ever needs to be repaired etc...
My VAS has been kept in check lately, so a Zion and or a Mi will only be overkill (I like overkill). I must say I really like the improvements that I have recently seen in the MI thread and I am happy to see on RBT's site that those improvements will be implemented in the new Zions.
"With Milaana complete, Zion will get the love that it deserves. A machine shop was contacted to build the steel fixtures required to machine the magnet holes to the precision required to ensure magnets do not fall out. Lesser strength magnets are also being considered as an option. Much of the learning from Milaana (routing, sanding, heater glass recess, heater screen assembly, adhesive bond improvements, etc) will now be applied to Zion. Once the jigs are completed the magnets can be applied and then the parts can be assembled and sanded. Once all six sides are sanded the routing can be completed, then machine sanding, then the 4 step dry / wet finishing process will complete the bodies. This will complete the wooden bodies and then assembly can begin. In the process, the handful of returns and partial builds will be completed for early customer acceptance testing."
