It's available for pre-order on some websites already. Not sure where you're located but Amazon seems to have the best price from what we have seen so far.
Amazon UK has it as well: https://www.amazon.co.uk/Hansa-Session-EP-10-Chvrches/dp/B07J368VL3/ref=sr_1_1?ie=UTF8&qid=1541959590&sr=8-1&keywords=hansa+session+chvrches
The nice thing about Amazon is you can usually just change .com to whatever your local site is in the URL to get the same product on your regional site. I did that to find it on Amazon Canada last night.
It's up on other sites as well, but these are ones I have ordered from in the past with no problems.
