It definitely won't be like the 2017 version with regards to getting you guys license keys. They should be on their way IMHO.
If you want to get on 2018 now then the best way would be just to use the in-built 30-day trial key until your official key arrives.
I'll investigate internally and find out why these are not sent out in advance so they are with you beforehand.
I've not heard of anyone that has gotten their 2018 key yet. Someone posted on printplanet that their reseller told them they did not have the product keys from Enfocus yet. Which is exactly what happened when 2017 was released.
All three of our keys arrived yesterday. Two from Enfocus and one from a reseller. Not made the switch just yet but so far much smoother than 2017.
Would like to understand what the delay is for everyone else though.
