It is my understanding that they are already in the mail.
Yes, I am a huge fan of the E1. I looked at the thread where people were having issues with the tubes, and I played with mine for a bit. I was able to get the tube to pop off of the metal connector, but it was pretty easy to get back on. They do need to be glued back on, or they will pop off again pretty easily. Once I put it back together and tried it, I did have to play with it for about 2 minutes to get it hitting right again... but it hits like it loves me again! Oh, and I am still on the original head, and still use the same ones from the review.

Of the 3 I have, only replaced one head!
So, I am really excited to know that these are coming. I with they came before VapeStock, but there will be enough there for me to enjoy.
