I think the time is near for the official V4 to be announced soon. All those big old players in the RTA game are releasing their new versions towards the end of the year.. So i hope, we see a PEEK and not wired base, cyclops style airflow CTRL, glass tank, and maybe wider wicking slots or adjustable (This could be done by DIY, so no biggie).
I will write the authentic's designers a mail in the next days, maybe i get a feedback. Most points i mentioned are quite popular demands.

We will see.
